The Cable News Network (CNN) is a liberal, secular 24-hour cable news channel in the United States. First started in 1980 by Ted Turner, it is a division of the Turner Broadcasting System, which is owned by TimeWarner.
From its origin as a cable-only service, CNN now broadcasts worldwide by satellite, with programs presented from studios in several countries in addition to their headquarters in Atlanta. Some regions receive locally produced opt-outs (under the name "CNN International"), and there are also broadcasts in Spanish, German, Italian, Croatian,Japanese, Turkish and Gaelic.
Where Fox News has succeeded, CNN has watched the steady fall in ratings.
CNN is owned by media mogul Ted Turner and made its debut in 1980 as the first US 24-hour news network.  During its early years it struggled to achieve the success and credibility of older news agencies, such as the BBC. However it achieved a great deal of recognition during its coverage of the first Gulf War during which it was the only news agency reporting during the initial night of the war. These events led to a movie, Live from Baghdad, which portrays the events. In September 2010, head of its U.S. network Jon Klein was fired. 
Well known bias
Conservative media critics, amongst other groups, rightly accuse CNN of promoting the liberal agenda with slant reporting,  mock and insult members of the Tea Party Movement.  Their coverage of the US Election of 2012 has also made alarm bells ring in the minds of true journalists. CNN has support the far-left Occupy Wall Street movement.
