The Cable News Network (CNN) is a liberal, 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, and Turkish. CNN was successful until around 2001, when Fox News began beating it in the ratings. Since then it has been failing.
CNN was founded by media mogul Ted Turner and made its debut on June 1, 1980 as the first 24-hour news network.  During its early years it struggled to achieve the success and credibility of older news agencies, such as the news divisions of ABC, NBC, CBS, and 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.  Ted Turner has sold CNN to Time Warner.
Ratings and reception
Although CNN was once the dominant network on cable news and one of the highest rated channels on cable television, this is no longer the case. In overall ratings, CNN is usually second place behind Fox News Channel but ahead of MSNBC.
By February 2014, CNN's average number of total viewers during the day from Monday to Sunday was 307,000 with 96,000 in the key 25 to 54 viewing demographic. In 2013, the network fell to a 20-year low in primetime ratings and experienced its second-lowest year ever in the 25 to 54 viewing demographic. That year, CNN also experienced its lowest total-day audience since 1992, and its lowest total-day 25 to 54 audience since 2000. 2014 closed out with CNN having all-time ratings lows. In primetime, the network suffered its worst-rated year in total viewers and its second-lowest in the 25 to 54 viewing demographic. In total day, CNN received its worst-rated year in the key demographic.
In 2001, the Media Research Center stated, "CNN certainly is less biased to the left than ABC, CBS and NBC".  However, it stated in the same report that "while much of its day-to-day reporting is more balanced than that offered on the broadcast networks, its news judgment usually follows the liberal agenda with conservatives relegated to reacting to it" and noted that it had some hosts on the network who clearly leaned to the left such as Larry King. And more recently, Conservative media critics, amongst other groups, rightly accuse CNN of promoting the liberal agenda with slanted reporting.  CNN has mocked and insulted 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 supported the far-left Occupy Wall Street movement. Van Jones is also a contributor on CNN. On October 2013 CNN mocked veterans as "Tea Party Crazies".
CNN has had some conservative commentators in the past. For example, Rowland Evans and Robert Novak were conservatives who hosted a show on CNN called Evans and Novak, later Evans, Novak, Hunt, and Shields, and Novak also co-hosted a debate program called Capital Gang, and he also co-hosted Crossfire, and was a political commentator on CNN's general coverage. Tucker Carlson, now at Fox News, was a CNN political analyst at one point. Another conservative on CNN was Kate O'Beirne. Barry Goldwater was a commentator for CNN at one point.
Today, Jeff Zucker, its new leader, openly despises Fox News and the Republican Party, in contrast to his predecessor Walter Isaacson, who tried to have balanced coverage, and another predecessor Tom Johnson, who was friends with Roger Ailes, the leader of Fox News.
