Cable News Network is a U.S. cable news channel founded in 1980 by American media mogul Ted Turner. Upon its launch, CNN was the first channel to provide 24-hour television news coverage, and the first all-news television channel in the United States. While the news channel has numerous affiliates, CNN primarily broadcasts from its headquarters at the CNN Center in Atlanta, the Time Warner Center in New York City, and studios in Washington, D.C., and Los Angeles. CNN is owned by parent company Time Warner, and the U.S. news channel is a division of the Turner Broadcasting System.
