The penny press was most noted for its price - only one cent per paper - while other contemporary newspapers were priced around six cents per issue. The exceptionally low price popularized the newspaper in America, and extended the influence of the newspaper media to the poorer classes. The penny press made the news and journalism more important, and also caused newspapers to begin to pay more attention to the public they served. Editors realized that the information that interested the upper class did not necessarily interest the penny-paying public. These new newspaper readers enjoyed information about police and criminal cases. The main revenue for the penny press was advertising while other newspapers relied heavily on high priced subscriptions to finance their activities.
