The '''mainstream media''' ('''MSM'''), at times referred to as the '''lamestream media'''<ref>https://www.politico.com/story/2009/11/palin-trashes-lamestream-media-029693</ref> for satirical purposes, are print and broadcast organizations that report on news events. The mainstream media dates back to the start of the nation where politicians and printers would prepare "broadside" news sheets. The format of the media has evolved to include multi-page newspapers printed on high-speed offset presses, radio, television and online websites. Traditionally, media has been supported by a combination of subscriptions, newsstand sales and advertising. These revenues pay the cost of distribution as well as the journalist journalists who write the content.
Because news gathering is expensive, over time the mainstream media has found ways to share content and to distribute the cost of journalism over a wider set of customers. Radio and television stations formed networks to share content. Print media formed organizations like United Press International and the Associated Press to share coverage and photos. Some newspapers share printing operations, and other media organizations such as Copley and Gannett have purchased a large number of newspapers resulting in shared administrative costs. Although media started with a large number of competing news outlets operated locally, over time, media ownership and control has become more centralized in large organizations. The increasingly [[liberal]] media organs censor the dissemination of honest news and repeatedly apply liberal [[double standard]]s.
