Harry J. LEHMAN, Petitioner,v.CITY OF SHAKER HEIGHTS et al.
No. 73—328.
Argued Feb. 26—27, 1974.
Decided June 25, 1974.

Syllabus
Petitioner, a candidate for state office, who was refused available advertising space on vehicles of a city transit system, brought this suit challenging the constitutionality of the municipal policy on which the refusal was based of not permitting political advertising but allowing other types of public transit advertising. The state courts declined to give petitioner relief, the Ohio Supreme Court holding that the city's refusal did not violate a candidate's free speech or equal protection rights. Held: The judgment is affirmed. Pp. 302—308.
34 Ohio St.2d 143, 296 N.E.2d 683, affirmed.
Mr. Justice BLACKMUN, joined by THE CHIEF JUSTICE, Mr. Justice WHITE, and Mr. Justice REHNQUIST, concluded that car card space on a city transit system is not a First Amendment forum and that here the decision to limit transit advertisements to innocuous and less controversial commercial and service-oriented advertising—thus minimizing chances of abuse, appearances of political favoritism, and the risk of imposing upon a captive audience—is within the city's discretion and involves no First or Fourteenth Amendment violation. Pp. 302—304.
Mr. Justice DOUGLAS concluded that petitioner, though free to express his views to a willing audience, has no constitutional right to force his message upon a captive audience, which uses public transit vehicles, not as a place for discussion, but only as a means of transport. Pp. 305—308.
Leonard J. Schwartz, Columbus, Ohio, for petitioner.
Paul R. Donaldson, Cleveland, Ohio, for respondents.
Mr. Justice BLACKMUN announced the judgment of the Court and an opinion, in which THE CHIEF JUSTICE, Mr. Justice WHITE, and Mr. Justice REHNQUIST join.


1
This case presents the question whether a city which operates a public rapid transit system and sells advertising space for car cards on its vehicles is required by the First and Fourteenth Amendments to accept paid political advertising on behalf of a candidate for public office.


2
In 1970, petitioner Harry J. Lehman was a candidate for the office of State Representative to the Ohio General Assembly for District 56. The district includes the city of Shaker Heights. On July 3, 1970, petitioner sought to promote his candidacy by purchasing car card space on the Shaker Heights Rapid Transit System for the months of August, September, and October. The general election was scheduled for November 3. Petitioner's proposed copy contained his picture and read:


3
'HARRY J. LEHMAN IS OLDFASHIONED! ABOUT HONESTY, INTEGRITY AND GOOD GOVERNMENT


4
'State Representative—District 56 ( ) Harry J. Lehman.' App.      39A.


5
Advertising space on the city's transit system is managed by respondent Metromedia, Inc., as exclusive agent under contract with the city. The agreement between the city and Metromedia provides:


6
'15. . . . The CONTRACTOR shall not place political      advertising in or upon any of the said CARS or in, upon or about any other additional and further space granted      hereunder.'1


7
When petitioner applied for space,2 he was informed by Metromedia that, although space was then available, the management agreement with the city did not permit political advertising.3 The system, however, accepted ads from cigarette companies, banks, savings and loan associations, liquor companies, retail and service establishments, churches, and civic and public-service oriented groups.4 There was uncontradicted testimony at the trial that during the 26 years of public operation, the Shaker Heights system, pursuant to city council action, had not accepted or permitted any political or public issue advertising on its vehicles. App. 30A—32A.


8
When petitioner did not succeed in his effort to have his copy accepted, he sought declaratory and injunctive relief in the state courts of Ohio without success. The Supreme Court of Ohio concluded that 'the constitutionally protected right of free speech with respect to forums for oral speech, or the dissemination of literature on a city's streets, does not extend to commercial or political advertising on rapid transit vehicles.' 34 Ohio St.2d 143, 145—146, 296 N.E.2d 683, 685 (1973). There was no equal protection violation, the court said, because, '(a)s a class, all candidates for political office are treated alike under the Shaker's Heights Rapid Transit System's commercial advertising policy.' Id., at 148, 296 N.E.2d, at 686. The three dissenting justices viewed the transit system's advertising space as a free speech forum and would have held that no valid governmental interest was furthered by the differential treatment between political and other advertising. A policy excluding political advertisements, in their view, would therefore deny political advertisers the equal protection of the law. We granted certiorari in order to consider the important First and Fourteenth Amendment question the case presented.5 414 U.S. 1021, 94 S.Ct. 443, 38 L.Ed.2d 312 (1973).


9
It is urged that the car cards here constitute a public forum protected by the First Amendment, and that there is a guarantee of nondiscriminatory access to such publicly owned and controlled areas of communication 'regardless of the primary purpose for which the area is dedicated.' Brief for Petitioner 14.


10
We disagree. In Packer Corp. v. Utah, 285 U.S. 105, 110, 52 S.Ct. 273, 274, 76 L.Ed. 643 (1932), Mr. Justice Brandeis, in speaking for a unanimous Court, recognized that 'there is a difference which justifies the classification between display advertising and that in periodicals or newspapers.' In Packer the Court upheld a Utah statute that made it a misdemeanor to advertise cigarettes on "any bill board, street car sign, street car, . . . placard," but exempted dealers' signs on their places of business and cigarette advertising "in any newspaper, magazine, or periodical." Id., at 107, 52 S.Ct. at 273. The Court found no equal protection violation. It reasoned that viewers of billboards and streetcar signs had no 'choice or volition' to observe such advertising and had the message 'thrust upon them by all the arts and devices that skill can produce. . . . The radio can be turned off, but not so the billboard or street car placard.' Id., at 110, 52 S.Ct., at 274—275. 'The streetcar audience is a captive audience. It is there as a matter of necessity, not of choice.' Public Utilities Comm'n v. Pollak, 343 U.S. 451, 468, 72 S.Ct. 813, 823, 96 L.Ed. 1068 (1952) (Douglas, J., dissenting). In such situations, '(t)he legislature may recognize degrees of evil and adapt its legislation accordingly.' Packer Corp. v. Utah, 285 U.S., at 110, 52 S.Ct. at 275. Cf. Breard v. Alexandria, 341 U.S. 622, 71 S.Ct. 920, 95 L.Ed. 1233 (1951).


11
These situations are different from the traditional settings where First Amendment values inalterably prevail. Lord Dunedin, in M'Ara v. Magistrates of Edinburgh, (1913) Sess.Cas. 1059, 1073 1074, said: '(T)he truth is that open spaces and public places differ very much in their character, and before you could say whether a certain thing could be done in a certain place you would have to know the history of the particular place.' Although American constitutional jurisprudence, in the light of the First Amendment, has been jealous to preserve access to public places for purposes of free speech, the nature of the forum and the conflicting interests involved have remained important in determining the degree of protection afforded by the Amendment to the speech in question. See, e.g., Cox v. New Hampshire, 312 U.S. 569, 61 S.Ct. 762, 85 L.Ed. 1049 (1941); Breard v. Alexandria, supra; Poulos v. New Hampshire, 345 U.S. 395, 73 S.Ct. 760, 97 L.Ed. 1105 (1953); Cox v. Louisiana, 379 U.S. 559, 85 S.Ct. 476, 13 L.Ed.2d 487 (1965); Adderley v. Florida, 385 U.S. 39, 87 S.Ct. 242, 17 L.Ed.2d 149 (1966); Red Lion Broadcasting Co. v. FCC, 395 U.S. 367, 89 S.Ct. 1794, 23 L.Ed.2d 371 (1969); Police Department of Chicago v. Mosley, 408 U.S. 92, 92 S.Ct. 2286, 33 L.Ed.2d 212 (1972); Grayned v. City of Rockford, 408 U.S. 104, 92 S.Ct. 2294, 33 L.Ed.2d 222 (1972); Columbia Broadcasting System, Inc. v. Democratic National Committee, 412 U.S. 94, 93 S.Ct. 2080, 36 L.Ed.2d 772 (1973); Pittsburgh Press Co. v. Pittsburgh Comm'n on Human Relations, 413 U.S. 376, 93 S.Ct. 2553, 37 L.Ed.2d 669 (1973).


12
Here, we have no open spaces, no meeting hall, park, street corner, or other public thoroughfare. Instead, the city is engaged in commerce. It must provide rapid, convenient, pleasant, and inexpensive service to the commuters of Shaker Heights. The car card space, although incidental to the provision of public transportation, is a part of the commercial venture. In much the same way that a newspaper or periodical, or even a radio or television station, need not accept every proffer of advertising from the general public, a city transit system has discretion to develop and make reasonable choices concerning the type of advertising that may be displayed in its vehicles. In making these choices, this Court has held that a public utility 'will be sustained in its protection of activities in public places when those activities do not interfere with the general public convenience, comfort and safety.' Public Utilities Comm'n v. Pollak, 343 U.S., at 464—465, 72 S.Ct. at 821.


13
Because state action exists, however, the policies and practices governing access to the transit system's advertising space must not be arbitrary, capricious, or invidious. Here, the city has decided that '(p)urveyors of goods and services saleable in commerce may purchase advertising space on an equal basis, whether they be house builders or butchers.' 34 Ohio St.2d, at 146, 296 N.E.2d, at 685. This decision is little different from deciding to impose a 10-, 25-, or 35-cent fare, or from changing schedules or the location of bus stops, Public Utilities Comm'n v. Pollak, 343 U.S., at 465, 72 S.Ct. at 822. Revenue earned from long-term commercial advertising could be jeopardardized by a requirement that short-term candidacy or issue-oriented advertisements be displayed on car cards. Users would be subjected to the blare of political propaganda. There could be lurking doubts about favoritism, and sticky administrative problems might arise in parceling out limited space to eager politicians. In these circumstances, the managerial decision to limit car card space to innocuous and less controversial commercial and service oriented advertising does not rise to the dignity of a First Amendment violation. Were we to hold to the contrary, display cases in public hospitals, libraries, office buildings, military compounds, and other public facilities immediately would become Hyde Parks open to every would-be pamphleteer and politician. This the Constitution does not require.


14
No First Amendment forum is here to be found. The city consciously has limited access to its transit system advertising space in order to minimize chances of abuse, the appearance of favoritism, and the risk of imposing upon a captive audience. These are reasonable legislative objectives advanced by the city in a proprietary capacity. In these circumstances, there is no First or Fourteenth Amendment violation.


15
The judgment of the Supreme Court of Ohio is affirmed.


16
It is so ordered.


17
Affirmed.


18
Mr. Justice DOUGLAS, concurring.


19
Petitioner, a candidate for state office, attempted to purchase space for paid political advertising on vehicles of the Shaker Heights Rapid Transit System, a system owned and operated by the city of Shaker Heights, Ohio. Metromedia, Inc., the exclusive advertising agent for the system, refused petitioner the space on the basis of a contract with the system prohibiting the acceptance of political advertisements. Petitioner unsuccessfully sought injunctive relief in the state courts to restrain the city and Metromedia from refusing his advertising.


20
The petitioner contends that, by selling advertising space, the city has turned its buses into free speech forums and the city is now prohibited by the First Amendment, applicable to the States through the Fourteenth,1 from refusing space for political advertisements.


21
My Brother BRENNAN would find that '(a) forum for communication was voluntarily established when the city installed the physical facilities for the advertisements and, by contract with Metromedia, created the necessary administrative machinery for regulating access to that forum.' Post, at 314. If the streetcar or bus were a forum for communication akin to that of streets or public parks, considerable problems would be presented. 'The privilege of a citizen of the United States to use the streets and parks for communication of views on national questions may be regulated in the interest of all . . . but it must not, in the guise of regulation, be abridged or denied.' Hague v. CIO, 307 U.S. 496, 515—516, 59 S.Ct. 954, 964, 83 L.Ed. 1423 (1939). But a streetcar or bus is plainly not a park or sidewalk or other meeting place for discussion, any more than is a highway. It is only a way to get to work or back home. The fact that it is owned and operated by the city does not without more make it a forum.


22
Bus and streetcar placards are in the category of highway billboards which have long been used to display an array of commercial and political messages. But this particular form of communication has been significantly curtailed by state regulation adopted pursuant to the Highway Beautification Act of 1965, 23 U.S.C. § 131, which conditions certain federal highway funds upon strict regulation of highway advertising. Ohio is among the States which have sought to protect the interests of their motorists2 by enacting regulations pursuant to the Act. Ohio Rev.Code Ann. § 5516.01 et seq. (Supp.1973). The fact that land on which a billboard rests is municipal land does not curtail or enhance such regulatory schemes.


23
If a bus is a forum it is more akin to a newspaper than to a park. Yet if a bus is treated as a newspaper, than, as we hold this date, Miami Herald Publishing Co. v. Tornillo, 418 U.S. 241, 94 S.Ct. 2831, 41 L.Ed.2d 730, the owner cannot be forced to include in his offerings news or other items which outsiders may desire but which the owner abhors. Newspaper cases are cited to support petitioner's claim. The First Amendment, however, draws no distinction between press privately owned, and press owned otherwise. And if we are to turn a bus or streetcar into either a newspaper or a park, we take great liberties with people who because of necessity become commuters and at the same time captive viewers or listeners.


24
In asking us to force the system to accept his message as a vindication of his constitutional rights, the petitioner overlooks the constitutional rights of the commuters. While petitioner clearly has a right to express his views to those who wish to listen, he has no right to force his message upon an audience incapable of declining to receive it. In my view the right of the commuters to be free from forced intrusions on their privacy precludes the city from transforming its vehicles of public transportation into forums for the dissemination of ideas upon this captive audience.


25
Buses are not recreational vehicles used for Sunday chautauquas as a public park might be used on holidays for such a purpose; they are a practical necessity for millions in our urban centers. I have already stated this view in my dissent in Public Utilities Comm'n v. Pollak, 343 U.S. 451, 469, 72 S.Ct. 813, 824, 96 L.Ed. 1068, involving the challenge by some passengers to the practice of broadcasting radio programs over loudspeakers in buses and streetcars: 'One who tunes in on an offensive program at home can turn it off or tune in another station, as he wishes. One who hears disquieting or unpleasant programs in public places, such as restaurants, can get up and leave. But the man on the streetcar has no choice but to sit and listen, or perhaps to sit and to try not to listen.' There is no difference when the message is visual, not auricular. In each the viewer or listener is captive.


26
I agree with Mr. Justice Brandeis who, quoting from a Utah State Court decision,3 said that the visual message in streetcars is no different, for "(a)dvertisements of this sort are constantly before the eyes of observers on the streets and in street cars to be seen without the exercise of choice or volition on their part. Other forms of advertising are ordinarily seen as a matter of choice on the part of the observer. . . . In the case of newspapers and magazines, there must be some seeking by the one who is to see and read the advertisement. The radio can be turned off, but not so the billboard or street car placard." Packer Corp. v. Utah, 285 U.S. 105, 110, 52 S.Ct. 273, 274, 76 L.Ed. 643.


27
I do not view the content of the message as relevant either to petitioner's right to express it or to the commuters' right to be free from it. Commercial advertisements may be as offensive and intrusive to captive audiences as any political message. But the validity of the commercial advertising program is not before us since we are not faced with one complaining of an invasion of privacy through forced exposure to commercial ads. Since I do not believe that petitioner has any constitutional right to spread his message before this captive audience, I concur in the Court's judgment.


28
Mr. Justice BRENNAN, with whom Mr. Justice STEWART, Mr. Justice MARSHALL, and Mr. Justice POWELL join, dissenting.


29
The city of Shaker Heights owns and operates the Shaker Heights Rapid Transit System, an interurban electric railroad line consisting of approximately 55 transit cars which transport passengers between Shaker Heights and Cleveland. Each of the cars contains 20 interior advertising spaces available for lease through the Metro Transit Division of Metromedia, Inc., the transit system's exclusive advertising agent. By agreement with the city, Metromedia accepts commercial and public service advertising, but will not accept 'political advertising.'


30
Prior to Ohio's 1970 general election, Harry J. Lehman, a candidate for the office of State Representative to the Ohio General Assembly for the 56th District, attempted to lease advertising space on the Shaker Heights Rapid Transit System, because, as he later testified, 'the vast majority of its six to eight thousand riders each day are residents of the district . . ..' (App. 14A). Although advertising space was available and Lehman's proposed advertisement1 met Metromedia's copy standards,2 rental space was nevertheless denied Lehman on the sole ground that Metromedia's contract with the city forbids acceptance of 'political advertising.'


31
After an unsuccessful attempt to persuade the city to alter its ban against political advertisements, Lehman commenced this action in the Court of Common Pleas for Cuyahoga County, Ohio, seeking declaratory and injunctive relief on the ground that the city's policy of prohibiting political advertisements infringed his freedom of speech and denied him equal protection of the laws. Finding no constitutional infirmities, the trial court denied relief and was affirmed by both the Cuyahoga County Court of Appeals and the Supreme Court of Ohio.


32
I would reverse. In my view, the city created a forum for the dissemination of information and expression of ideas when it accepted and displayed commercial and public service advertisements on its rapid transit vehicles. Having opened a forum for communication, the city is barred by the First and Fourteenth Amendments from discriminating among forum users solely on the basis of message content.


33
* The message Lehman sought to convey concerning his candidacy for public office was unquestionably protected by the First Amendment. That constitutional safeguard was fashioned to encourage and nurture 'uninhibited, robust, and wide-open' self-expression, particularly in matters of governing importance. New York Times Co. v. Sullivan, 376 U.S. 254, 270, 84 S.Ct. 710, 720, 11 L.Ed.2d 686 (1964). 'For speech concerning public affairs is more than self-expression; it is the essence of self-government.' Garrison v. Louisiana, 379 U.S. 64, 74—75, 85 S.Ct. 209, 216, 13 L.Ed.2d 125 (1964). 'The maintenance of the opportunity for free political discussion to the end that government may be responsive to the will of the people and that changes may be obtained by lawful means, an opportunity essential to the security of the Republic, is a fundamental principle of our constitutional system.' Stromberg v. California, 283 U.S. 359, 369, 51 S.Ct. 532, 536, 75 L.Ed. 1117 (1931). The fact that the message is proposed as a paid advertisement does not diminish the impregnable shelter afforded by the First Amendment. See New York Times Co. v. Sullivan, supra, 376 U.S., at 271, 84 S.Ct. at 721.


34
Of course, not even the right of political self-expression is completely unfettered. As we stated in Cox v. Louisiana, 379 U.S. 536, 554, 85 S.Ct. 453, 464, 13 L.Ed.2d 471 (1965):


35
'The rights of free speech and assembly, while fundamental in      our democratic society, still do not mean that everyone with      opinions or beliefs to express may address a group at any      public place and at any time. The constitutional guarantee of      liberty implies the existence of an organized society      maintaining public order, without which liberty itself would      be lost in the excesses of anarchy.'


36
Accordingly, we have repeatedly recognized the constitutionality of reasonable 'time, place and manner' regulations which are applied in an evenhanded fashion. See, e.g., Police Department of Chicago v. Mosley, 408 U.S. 92, 98, 92 S.Ct. 2286, 2291, 33 L.Ed.2d 212 (1972); Grayned v. City of Rockford, 408 U.S. 104, 115, 92 S.Ct. 2294, 2302, 33 L.Ed.2d 222 (1972); Cox v. Louisiana, supra, 379 U.S., at 554—555, 85 S.Ct. at 464—465; Poulos v. New Hampshire, 345 U.S. 395, 398, 73 S.Ct. 760, 762, 97 L.Ed. 1105 (1953); Cox v. New Hampshire, 312 U.S. 569, 575—576, 61 S.Ct. 762, 765—766, 85 L.Ed. 1049 (1941); Schneider v. State of N.J., 308 U.S. 147, 160, 60 S.Ct. 146, 150, 84 L.Ed. 155 (1939).


37
Focusing upon the propriety of regulating 'place,' the city of Shaker Heights attempts to justify its ban against political advertising by arguing that the interior advertising space of a transit car is an inappropriate forum for political expression and debate. Brief for Respondents 7. To be sure, there are some public places which are so clearly committed to other purposes that their use as public forums for communication is anomalous. For example, '(t) here may be some instances in which assemblies and petitions for redress of grievances are not consistent with other necessary purposes of public property. A noisy meeting may be out of keeping with the serenity of the statehouse or the quiet of the courthouse. No one . . . would suggest that the Senate gallery is the proper place for a vociferous protest rally. And in other cases it may be necessary to adjust the right to petition for redress of grievances to the other interests inhering in the uses to which the public property is normally pub.' Adderley v. Florida, 385 U.S. 39, 54, 87 S.Ct. 242, 250, 17 L.Ed.2d 149 (1966) (Douglas, J., dissenting). The determination of whether a particular type of public property or facility constitutes a 'public forum' requires the Court to strike a balance between the competing interests of the government, on the one hand, and the speaker and his audience, on the other.3 Thus, the Court must assess the importance of the primary use to which the public property or facility is committed and the extent to which that use will be disrupted if access for free expression is permitted.


38
Applying these principles, the Court has long recognized the public's right of access to public streets and parks for expressive activity. As Mr. Justice Roberts wrote in Hague v. CIO, 307 U.S. 496, 515—516, 59 S.Ct. 954, 964, 83 L.Ed. 1423 (1939):


39
'Wherever the title of streets and parks may rest, they have      immemorially been held in trust for the use of the public      and, time out of mind, have been used for purposes of      assembly, communicating thoughts between citizens, and      discussing public questions. Such use of the streets and      public places has, from ancient times, been a part of the      privileges, immunities, rights, and liberties of citizens.      The privilege of a citizen of the United States to use the      streets and parks for communication of views on national      questions may be regulated in the interest of all; it is not      absolute, but relative, and must be exercised in      subordination to the general comfort and convenience, and in      consonance with peace and good order; but it must not, in the      guise of regulation, be abridged or denied.'


40
See also Jamison v. Texas, 318 U.S. 413, 63 S.Ct. 669, 87 L.Ed. 869 (1943); Cox v. Louisiana, supra. More recently, the Court has added state capitol grounds to the list of public forums compatible with free speech, free assembly, and the freedom to petition for redress of grievances, Edwards v. South Carolina, 372 U.S. 229, 83 S.Ct. 680, 9 L.Ed.2d 697 (1963), but denied similar status to the curtilage of a jailhouse, on the ground that jails are built for security and thus need not be opened to the general public, Adderley v. Florida, 385 U.S. 39, 87 S.Ct. 242, 17 L.Ed.2d 149 (1966).4


41
In the circumstances of this case, however, we need not decide whether public transit cars must be made available as forums for the exercise of First Amendment rights. By accepting commercial and public service advertising, the city effectively waived any argument that advertising in its transit cars is incompatible with the rapid transit system's primary function of providing transportation. A forum for communication was voluntarily established when the city installed the physical facilities for the advertisements and, by contract with Metromedia, created the necessary administrative machinery for regulating access to that forum.5


42
The plurality opinion, however, contends that as long as the city limits its advertising space to 'innocuous and less controversial commercial and service oriented advertising,' no First Amendment forum is created. Ante, at 304. I find no merit in that position. Certainly, noncommercial public service advertisements convey messages of public concern and are clearly protected by the First Amendment. And while it is possible that commercial advertising may be accorded less First Amendment protection than speech concerning political and social issues of public importance, compare Valentine v. Chrestensen, 316 U.S. 52, 62 S.Ct. 920, 86 L.Ed. 1262 (1942), with Schneider v. State of N.J., 308 U.S. 147, 60 S.Ct. 146, 84 L.Ed. 155 (1939), and Breard v. City of Alexandria, 341 U.S. 622, 71 S.Ct. 920, 95 L.Ed. 1233 (1951), with Martin v. City of Struthers, 319 U.S. 141, 63 S.Ct. 862, 87 L.Ed. 1313 (1943), it is 'speech' nonetheless, often communicating information and ideas found by many persons to be controversial.6 There can be no question that commercial advertisements, when skillfully employed, are powerful vehicles for the exaltation of commercial values. Once such messages have been accepted and displayed, the existence of a forum for communication cannot be gainsaid. To hold otherwise, and thus sanction the city's preference for bland commercialism and noncontroversial public service messages over 'uninhibited, robust, and wide-open' debate on public issues, would reverse the traditional priorities of the First Amendment.7

II

43
Once a public forum for communication has been established, both free speech and equal protection principles prohibit discrimination based solely upon subject matter or content.8 See, e.g., Police Department of Chicago v. Mosley, 408 U.S., at 95—96, 92 S.Ct., at 2289—2290; Cox v. Louisiana, 379 U.S. 559, 581, 85 S.Ct. 476, 470, 13 L.Ed.2d 487 (1965) (Black, J., concurring and dissenting); Fowler v. Rhode Island, 345 U.S. 67, 73 S.Ct. 526, 97 L.Ed. 828 (1953); Niemotko v. Maryland, 340 U.S. 268, 272—273, 71 S.Ct. 325, 327—328, 95 L.Ed. 267, 280 (1951).


44
'Necessarily, then, under the Equal Protection Clause, not to      mention the First Amendment itself, government may not grant      the use of a forum to people whose views it finds acceptable,      but deny use to those wishing to express less favored or more      controversial views. And it may not select which issues are      worth discussing or debating in public facilities. There is      an 'equality of status in the field of ideas,' and government      must afford all points of view an equal opportunity to be      heard. Once a forum is opened up to assembly or speaking by      some groups, government may not prohibit others from      assembling or speaking on the basis of what they intend to      say. Selective exclusions from a public forum may not be      based on content alone, and may not be justified by reference      to content alone.' Police Department of Chicago v. Mosley,      supra, 408 U.S., at 96, 92 S.Ct., at 2290 (footnote omitted).


45
That the discrimination is among entire classes of ideas, rather than among points of view within a particular class, does not render it any less odious. Subject matter or content censorship in any form is forbidden.9


46
To insure that subject matter or content is not the sole basis for discrimination among forum users, all selective exclusions from a public forum must be closely scrutinized and countenanced only in cases where the government makes a clear showing that its action was taken pursuant to neutral 'time, place and manner' regulations, narrowly tailored to protect the government's substantial interest in preserving the viability and utility of the forum itself. See, e.g., Police Department of Chicago v. Mosley, supra, 408 U.S., at 98—102, 92 S.Ct. at 2291—2294; Grayned v. City of Rockford, 408 U.S., at 115 117, 92 S.Ct. at 2302—2304; Shuttlesworth v. Birmingham, 394 U.S. 147, 152—153, 89 S.Ct. 935, 939—940, 22 L.Ed.2d 162 (1969); Tinker v. Des Moines School District, 393 U.S. 503, 508, 514, 89 S.Ct. 733, 737, 740, 21 L.Ed.2d 731 (1969); cf. Dunn v. Blumstein, 405 U.S. 330, 336—337, 92 S.Ct. 995, 999—1000, 31 L.Ed.2d 274 (1972); Williams v. Rhodes, 393 U.S. 23, 31, 89 S.Ct. 5, 10, 21 L.Ed.2d 24 (1968). The city has failed to discharge that heavy burden in the present case.


47
The Court's special vigilance is triggered in this case because of the city's undisputed ban against political advertising in its transit cars. Commercial and public service advertisements are routinely accepted for display, while political messages are absolutely prohibited. Few examples are required to illustrate the scope of the city's policy and practice. For instance, a commercial advertisement peddling snowmobiles would be accepted, while a counter-advertisement calling upon the public to support legislation controlling the environmental destruction and noise pollution caused by snowmobiles would be rejected. Alternatively, a public service ad by the League of Women Voters would be permitted, advertising the existence of an upcoming election and imploring citizens to vote, but a candidate, such as Lehman, would be barred from informing the public about his candidacy, qualifications for office, or position on particular issues. These, and other examples,10 make perfectly clear that the selective exclusion of political advertising is not the product of evenhanded application of neutral 'time, place, and manner' regulations. Rather, the operative—and constitutionally impermissible—distinction is the message on the sign. That conclusion is not dispelled by any of the city's asserted justifications for selectively excluding political advertising.


48
The city contends that its ban against political advertising is bottomed upon its solicitous regard for 'captive riders' of the rapid transit system, who are 'forced to endure the advertising thrust upon (them).' Brief for Respondents 8. Since its rapid transit system is primarily a mode of transportation, the city argues that it may prohibit political advertising in order to shield its transit passengers from sometimes controversial or unsettling speech. Whatever merit the city's argument might have in other contexts, it has a hollow ring in the present case, where the city has voluntarily opened its rapid transit system as a forum for communication. In that circumstance, the occasional appearance of provocative speech should be expected. Indeed, the Court has recognized that 'a function of free speech under our system of government is to invite dispute. . . . Speech is often provocative and challenging. It may strike at prejudices and preconceptions and have profound unsettling effects as it presses for acceptance of an idea.' Terminiello v. City of Chicago, 337 U.S. 1, 4, 69 S.Ct. 894, 806, 93 L.Ed. 1131 (1949).


49
The line between ideological and nonideological speech is impossible to draw with accuracy. By accepting commercial and public service advertisements, the city opened the door to 'sometimes controversial or unsettling speech' and determined that such speech does not unduly interfere with the rapid transit system's primary purpose of transporting passengers. In the eyes of many passengers, certain commercial or public service messages11 are as profoundly disturbing as some political advertisements might be to other passengers. There is certainly no evidence in the record of this case indicating that political advertisements, as a class, are so disturbing when displayed that they are more likely than commercial or public service advertisements to impair the rapid transit system's primary function of transportation. In the absence of such evidence, the city's selective exclusion of political advertising constitutes an invidious discrimination on the basis of subject matter, in violation of the First and Fourteenth Amendment.


50
Moreover, even if it were possible to draw a manageable line between controversial and noncontroversial messages, the city's practice of censorship for the benefit of 'captive audiences' still would not be justified.12 This is not a case where an unwilling or unsuspecting rapid transit rider is powerless to avoid messages he deems unsettling. The advertisements accepted by the city and Metromedia are not broadcast over loudspeakers in the transit cars. The privacy of the passengers is not, therefore, dependent upon their ability 'to sit and to try not to listen.' Public Utilities Comm'n v. Pollak, 343 U.S. 451, 469, 72 S.Ct. 813, 824, 96 L.Ed. 1068 (1952) (DOUGLAS, J., dissenting); cf. Kovacs v. Cooper, 336 U.S. 77, 69 S.Ct. 448, 93 L.Ed. 513 (1949); Saia v. New York, 334 U.S. 558, 562, 68 S.Ct. 1148, 1150, 92 L.Ed. 1574 (1948). Rather, all advertisements accepted for display are in written form. Transit passengers are not forced or compelled to read any of the messages, nor are they 'incapable of declining to receive (them),' ante, at 307 (Douglas, J., concurring). Should passengers chance to glance at advertisements they find offensive, they can 'effectively avoid further bombardment of their sensibilities simply by averting their eyes.' Cohen v. California, 403 U.S. 15, 21, 91 S.Ct. 1780, 1786, 29 L.Ed.2d 284 (1971). Surely that minor inconvenience is a small price to pay for the continued preservation of so precious a liberty as free speech.


51
The city's remaining justification is equally unpersuasive. The city argues that acceptance of 'political advertisements in the cars of the Shaker Heights rapid transit, would suggest, on the one hand, some political favoritism is being granted to candidates who advertise, or, on the other hand, that the candidate so advertised is being supported or promoted by the government of the City.' Brief for Respondents 8. Clearly, such ephemeral concerns do not provide the city with carte blanche authority to exclude an entire category of speech from a public forum. 'These pragmatic hurdles are no more relevant to a public forum when it is a motor coach than they are to a public park or a school auditorium. The endorsement of an opinion expressed in an advertisement on a motor coach is no more attributable to the transit district than the view of a speaker in a public park is to the city administration or the tenets of an organization using school property for meetings is to the local school board.' Wirta v. Alameda-Contra Costa Transit District, 68 Cal.2d 51, 61, 64 Cal.Rptr. 430, 437, 434 P.2d 982, 989 (1967). The city has introduced no evidence demonstrating that its rapid transit passengers would naively think otherwise. And though there may be 'lurking doubts about favoritism,' ante, at 304, the Court has held that '(n)o such remote danger can justify the immediate and crippling impact on the basic constitutional rights involved in this case.' Williams v. Rhodes, 393 U.S., at 33, 89 S.Ct., at 12.


52
Moreover, neutral regulations, which do not distinguish among advertisements on the basis of subject matter, can be narrowly tailored to allay the city's fears. The impression of city endorsement can be dispelled by requiring disclaimers to appear prominently on the face of every advertisement.13 And while problems of accommodating all potential advertisers may be vexing at times, the appearance of favoritism can be avoided by the evenhanded regulation of time, place, and manner for all advertising, irrespective of subject matter.


53
I would, therefore, reverse the judgment of the Supreme Court of Ohio and remand this case for further proceedings not inconsistent with this opinion.

 Metromedia has a written Metro Transit Advertising Copy Policy setting forth the following criteria:
'(1) Metro Transit Advertising will not display advertising copy that is false, misleading, deceptive and/or offensive to the moral standards of the community, or contrary to good taste. Copy which might be contrary to the best interests of the transit systems, or which might result in public criticism of the advertising industry and/or transit advertising will not be acceptable.
'(2) Metro Transit Advertising will not accept any political copy that pictorially, graphically or otherwise states or suggests that proponents or opponents of the persons or measures advertised are vulgar, greedy, immoral, monopolistic, illegal or unfair.
'(10) Political advertising will not be accepted on following systems: Shaker Rapid—Maple Heights—North Olmsted—Euclid, Ohio.' Shaker Heights' Exhibit A.

Copy which might be contrary to the best interests of the transit systems, or which might result in public criticism of the advertising industry and/or transit advertising will not be acceptable.
'(2) Metro Transit Advertising will not accept any political copy that pictorially, graphically or otherwise states or suggests that proponents or opponents of the persons or measures advertised are vulgar, greedy, immoral, monopolistic, illegal or unfair.

 Public-forum status has also been extended to municipal bus terminals, see Wolin v. Port of New York Authority, 392 F.2d 83 (CA2 1968), and railroad stations, see In re Hoffman, 67 Cal.2d 845, 64 Cal.Rptr. 97, 434 P.2d 353 (1967).


5
 My Brother DOUGLAS' analogy to billboard and newspaper advertising, ante, at 306—308, is not apropos in the circumstances of this case where the advertising display space is city owned and operated.


6
 There is some doubt concerning whether the 'commercial speech' distinction announced in Valentine v. Chrestensen, 316 U.S. 52, 62 S.Ct. 920, 86 L.Ed. 1262 (1942), retains continuing validity. Mr. Justice Douglas has remarked: 'The ruling was casual, almost offhand. And it has not survived reflection.' Cammarano v. United States, 358 U.S. 498, 514, 79 S.Ct. 524, 534, 3 L.Ed.2d 462 (1959) (concurring opinion). See also Pittsburgh Press Co. v. Pittsburgh Commission on Human Relations, 413 U.S. 376, 393, 93 S.Ct. 2553, 2562, 37 L.Ed.2d 669 (1973) (Burger, C.J., dissenting); id., at 401, 93 S.Ct. at 2565 (Douglas, J., dissenting); id., at 401, 93 S.Ct. at 2566 (Stewart, J., dissenting). That question, however, need not be decided in this case. It is sufficient for the purpose of public forum analysis merely to recognize that commercial speech enjoys at least some degree of protection under the First Amendment, without reaching the more difficult question concerning the amount of protection afforded.


7
 Other courts have reached the same conclusion on nearly identical facts. See Kissinger v. New York City Transit Authority, 274 F.Supp. 438 (S.D.N.Y.1967); Hillside Community Church, Inc. v. City of Tacoma, 76 Wash.2d 63, 455 P.2d 350 (1969); Wirta v. Alameda-Contra Costa Transit District, 68 Cal.2d 51, 64 Cal.Rptr. 430, 434 P.2d 982 (1967).


8
 The plurality opinion's reliance upon Packer Corp. v. Utah, 285 U.S. 105, 52 S.Ct. 273, 76 L.Ed. 643 (1932), is misplaced. As Mr. Justice Douglas noted in Cammarano v. United States, supra, 358 U.S., at 513 n., 79 S.Ct., at 533 n. (concurring opinion): 'In Packer Corp. v. Utah, 285 U.S. 105, (52 S.Ct. 273, 76 L.Ed. 643), the First Amendment problem was not raised. The extent to which such advertising could be regulated consistently with the First Amendment (cf. Cantwell v. Connecticut, 310 U.S. 296 (60 S.Ct. 900, 84 L.Ed. 1213); Martin v. Struthers, 319 U.S. 141 (63 S.Ct. 862, 87 L.Ed. 1313); Breard v. Alexandria, 341 U.S. 622 (71 S.Ct. 920, 95 L.Ed. 1233); Roth v. United States, 354 U.S. 476 (77 S.Ct. 1304, 1 L.Ed.2d 1498) has therefore never been authoritatively determined.' See also n. 6, supra.


9
 The existence of other public forums for the dissemination of political messages is, of course, irrelevant. As the Court said in Schneider v. State of N.J., 308 U.S. 147, 163, 60 S.Ct. 146, 151, 84 L.Ed. 155 (1939), 'one is not to have the exercise of his liberty of expression in appropriate places abridged on the plea that it may be exercised in some other place.'


10
 In declaring unconstitutional an advertising policy remarkably similar to the city's policy in the present case, the California
Supreme Court detailed 'the paradoxical scope of the (transit) district's policy (banning political advertising)' in the following manner:
'A cigarette company is permitted to advertise the desirability of smoking its brand, but a cancer society is not entitled to caution by advertisement that cigarette smoking is injurious to health. A theater may advertise a motion picture that portrays sex and violence, but the Legion for Decency has no right to post a message calling for clean films. A lumber company may advertise its wood products, but a conservation group cannot implore citizens to write to the President or Governor about protecting our natural resources. An oil refinery may advertise its products, but a citizens' organization cannot demand enforcement of existing air pollution statutes. An insurance company may announce its available policies, but a senior citizens' club cannot plead for legislation to improve our social security program. The district would accept an advertisement from a television station that is commercially inspired, but would refuse a paid nonsolicitation message from a strictly educational television station. Advertisements for travel, foods, clothing, toiletries, automobiles, legal drugs—all these are acceptable, but the American Legion would not have the right to place a paid advertisement reading, 'Support Our Boys in Viet Nam. Send Holiday Packages," Wirta v. Alameda-Contra Costa Transit District, 68 Cal.2d 51, 57—58, 64 Cal.Rptr. 430, 434—435, 434 P.2d 982, 986—987 (1967).


11
 For example, the record indicates that church advertising was accepted for display on the Shaker Heights Rapid Transit System. See App. 26A.


12
 My Brother DOUGLAS' contrary view, that 'the right of the commuters to be free from forced intrusions on their privacy precludes the city from transforming its vehicles of public transportation into forums for the dissemination of ideas upon this captive audience,' irrespective of whether the speech in question is commercial or noncommercial, ante at 307, does not dispose of the First and Fourteenth Amendment issues in this case. The record reveals that the Shaker Heights Rapid Transit System provides advertising space on the outside as well as the inside of its cars. See App. 24A, Lehman was denied access to both. Whatever applicability a 'captive audience' theory may have to interior advertising, it simply cannot justify the city's refusal to rent Lehman exterior advertising space.


13
 Metro's current copy policy provides for such disclaimers in those city transit systems that accept political advertisements. See n. 2, supra, at (5).
