The Cable News Network (CNN) is an American basic cable and satellite television channel that is owned by the Turner Broadcasting System division of Time Warner. The 24-hour cable news channel was founded in 1980 by American media proprietor 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 sometimes referred to as CNN/U.S. to distinguish the American channel from its international counterpart, CNN International. As of August 2010, CNN is available in over 100 million U.S. households. Broadcast coverage extends to over 890,000 American hotel rooms, and the U.S. channel is also carried on cable and satellite in Canada. Globally, CNN programming airs through CNN International, which can be seen by viewers in over 212 countries and territories. As of August 2013, approximately 98,496,000 American households (86% of cable, satellite & telco customers) receive CNN. On January 28, 1986, CNN carried the only live television coverage of the launch and subsequent explosion of Space Shuttle Challenger, which killed all seven crew members on board. CNN's current weekday schedule consists mostly of rolling news programming during the afternoon and evening, followed by more in-depth news and interview programs during the evening and primetime hours. The network's morning programming consists of Early Start, an early-morning news program hosted by John Berman and Christine Romans, which is followed by New Day, the network's morning show, hosted by Chris Cuomo, Kate Bolduan and Michaela Pereira. Most of CNN's late-morning and early afternoon programming consists of CNN Newsroom, a rolling news program hosted in blocks by various anchors, but as of 2013, the network began to rework its daytime programming into more distinct programs, beginning with the spin-off of Ashleigh Banfield's hour-long block of Newsroom as Legal View in August 2013 (with an emphasis on legal issues and court cases), the introduction of Around the World, a new hour-long program focusing on international headlines, and a new hour of Newsroom hosted by Wolf Blitzer. Further changes to CNN's daytime lineup occurred on February 10, 2014, with the cancellation of Around the World, the move of Legal View to its former Noon ET time slot, the introduction of @thishour with John Berman and Michaela Pereira, and the re-launch of Blitzer's afternoon show as Wolf. CNN's late-afternoon and early-evening lineup consists of The Lead, hosted by Jake Tapper, The Situation Room with Wolf Blitzer, and Crossfire, a panel debate program hosted by S. E. Cupp, Stephanie Cutter, Newt Gingrich and Van Jones. The network's evening and primetime lineup shifts towards more in-depth programming, including Erin Burnett OutFront, Anderson Cooper 360°, and Piers Morgan Live. On Friday nights, the network airs the sport-related program Unguarded with Rachel Nichols. CNN's weekend lineup also consists primarily of Newsroom, along with the medical program Sanjay Gupta MD and Your Money. Weekend primatime is dedicated mostly to factual programming, including the reality series Anthony Bourdain: Parts Unknown, along with topical documentaries and specials under umbrella titles such as CNN Presents, CNN Special Investigations Unit, and CNN Films. The network's Sunday-morning lineup consists of a block of political programs, including Inside Politics with John King, State of the Union with Candy Crowley, Fareed Zakaria GPS, and Reliable Sources In December 2008, CNN introduced a new graphics package, a comprehensive redesign replacing the existing style that had been used since 2004. The design replaced the scrolling ticker that had been in use since 2001, with the ticker space now carrying headlines both manually put in and taken from the RSS feeds of CNN.com, and rebranded as 'the flipper'. The CNN logo itself has remained relatively unchanged since the channel's launch, except that it was originally displayed in yellow (later changing to the current red), a 3-D 'shadow' effect was removed, and other design choices were made to acclimate the logo for both modern times and advances in graphical technolog.
