§ 14. New York Associated Press.

This idea of news and the newspaper for its own sake, the unprecedented aggressiveness in news-gathering, and the blatant methods by which the cheap papers were popularized aroused the antagonism of the older papers, but created a competition which could not be ignored. Systems of more rapid news-gathering and distribution quickly appeared. Sporadic attempts at co-operation in obtaining news had already been made; in 1848 the Journal of Commerce, Courier and Enquirer, Tribune, Herald, Sun, and Express formed the New York Associated Press to Obtain news for the members jointly. Out of this idea grew other local, then state, and finally national associations. European news, which, thanks to steamship service, could now be obtained when but half as old as before, became an important feature. In the forties several papers sent correspondents abroad, and in the next decade this field was highly developed.   23
