The editor, usually reflecting the sentiment of a group or a faction, began to emerge as a distinct power. He closely followed the drift of events and expressed vigorous opinions. But as yet the principal discussions were contributed not by the editors but by "the master minds of the country." The growing importance of the newspaper was shown in the discussions preceding the Federal Convention, and notably in the countrywide debate on the adoption of the Constitution, in which the newspaper largely displaced the pamphlet. When Alexander Hamilton, James Madison, and John Jay united to produce the Federalist Essays, they chose to publish them in "The Independent Journal" and "The Daily Advertiser", from which they were copied by practically every paper in America long before they were made into a book.
