While the era of a distinctive and popular penny press was short-lived, it witnessed one of the most notable advances of the century in journalism. It stimulated newspaper enterprise throughout the entire country, and journals multiplied enormously. The era practically ended with the outbreak of the Civil War in 1861, which event caused a rise in the price of paper, a demand for expensive correspondence, telegraph news and battle scenes, and a consequent necessity for enlarged and quadrupled sheets. Many of the penny papers went up to a five-cent price under the stimulus of war excitement, the improved system of collecting news, and the added expense of publication. This era of phenomenal newspaper expansion extended even to the end of the century. It has witnessed the wonderful evolution of the newspaper in all its modern phases,—the advent of the Sunday newspaper; the growth of the daily sheet to mammoth proportions; the incorporation of the Associated Press, with its thousands of agents in every part of the country gathering and sending the minutest events of the day; correspondence from every quarter of the globe, and covering every field of activity; a highly improved and more independent editorship; a greatly enlarged, more active, and more conscientious reportorial staff; the coming of the interviewer, at first an impertinent pest, but now recognized as a valuable journalistic adjunct in reflecting opinions and sentiments not otherwise obtainable; the employment of the thousand and one new appliances for printing, such as stereotyping, electrotyping, improved types, typesetting machines, rapid presses, folding machines, etc. By 1883 a reaction came on in the prices of leading journals, and they were forced to reduce them by reason of the strong competition offered by the numerous and powerful two-cent journals which had come into being and had proven to be valuable properties. Indeed, this reaction did not leave the two-cent journals untouched, for it brought many of that class to a one-cent basis, with the claim that a consequently increased circulation would enhance the profits from advertising. This claim is a debatable one, and it may be safely said that most of the newspapers established near the end of the century have adopted a two-cent basis as a golden mean between the one-cent and three-cent journals.
