The term "simulcast" (describing simultaneous radio/television broadcast) was coined in 1948 by a press agent at WCAU-TV, Philadelphia. NBC and CBS had begun broadcasting a few programs both to their established nationwide radio audience and to the much smaller—though steadily-growing—television audience. NBC's "Voice of Firestone" is sometimes mentioned in this regard, but NBC's "Voice of Firestone Televues" program, reaching a small Eastern audience beginning in 1943, was a TV-only show, distinct from the radio "Voice of Firestone" broadcasts. Actual TV-AM radio simulcasts of the very same "Voice of Firestone" program began only on 5 September 1949. A documented candidate for first true simulcast may well be NBC's "We the People." Toscanini's NBC Symphony performance of 15 March 1952 is perhaps a first instance of radio/TV simulcasting of a concert, predating the much-heralded rock concert simulcasts beginning in the 1980s. It could, however, be argued that these Toscanini presentations--with admission controlled by NBC, as with all its programming--were no more "public concerts" than NBC's "Voice of Firestone" broadcasts beginning in 1949, or its "Band of America" programs, which were simulcast starting 17 October 1949. Likewise Toscanini's simulcast NBC presentation of two acts of Verdi's "Aida" on 3 April 1949.
