"Cable News Network (CNN) is a U.S. cable news channel founded in 1980 by 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."
