Cable News Network, almost always referred to by its initials CNN, is a major U.S. cable news network founded in 1980 by Ted Turner. Upon its launch, CNN was the first network to provide 24-hour television news coverage, and the first all-news television network in the United States. While the news network 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 its parent company Time Warner, and the U.S. news network is a division of the Turner Broadcasting System.
