24-hour news channels are devoted to current events around the clock. They are often referred to as "cable news" channels. The originator of this format from which the name derives is CNN (which following its 1980 launch, spun off other national and international networks using the brand such as CNN International, CNN en Español, and CNN-IBN), originally standing for Cable News Network in reference to the then-new phenomenon of cable television. As satellite and other forms of television have evolved, the term "cable news" has become something of an anachronism, but is still in common use; many other television channels have since been established, such as BBC World News, BBC News Channel, Sky News, Al Jazeera, Newsmax TV, ABC News 24, France 24, STAR News, Fox News, and MSNBC. Some news channels specialize even further, such as ESPNews (sports news; sister channel to ESPN); The Weather Channel (weather, although its status as a specialty news channel has become ambiguous due to its recent incorporation of non-news entertainment programming) and WeatherNation (weather); CNBC, Bloomberg Television, and Fox Business Network (financial news).
