Cable News Network (CNN) is an American basic cable and satellite television news channel owned by the Turner Broadcasting System division of Time Warner. It was founded in 1980 by American media proprietor Ted Turner as a 24-hour cable news channel. Upon its launch, CNN was the first television channel to provide 24-hour news coverage, and was the first all-news television channel in the United States.

While the news channel has numerous affiliates, CNN primarily broadcasts from the Time Warner Center in New York City, and studios in Washington, D.C. and Los Angeles. Its headquarters at the CNN Center in Atlanta is only used for weekend programming. CNN is sometimes referred to as CNN/U.S. (or CNN Domestic) to distinguish the American channel from its international sister network, CNN International.

The Cable News Network was launched at 5:00 p.m. Eastern Time on June 1, 1980. After an introduction by Ted Turner, the husband and wife team of David Walker and Lois Hart anchored the channel's first newscast. A companion channel, CNN2, was launched on January 1, 1982 and featured a continuous 24-hour cycle of 30-minute news broadcasts. The channel, which later became known as CNN Headline News and is now known as simply HLN, eventually focused on live news coverage supplemented by personality-based programs during the evening and primetime hours.
