BBC World News is the BBC's international news and current affairs television channel. It has the largest audience of any BBC channel in the world. Launched on 11 March 1991 as the BBC World Service Television outside of Europe, with its name changed to BBC World in 1995 and to BBC World News in 2008, it broadcasts for 24-hours with television programming including BBC News bulletins, documentaries, lifestyle programmes and interviews. Its main global competitor is CNN International, though it also competes with other major news broadcasting companies. It employs more correspondents, reporters, and international bureaus than any other news channel.
Unlike the BBC's domestic channels, BBC World News is not funded by a licence fee. Instead, it is funded commercially by advertising.
The channel's present name was introduced on 21 April 2008 as part of a £550,000 rebranding of the BBC's news output and visual identity. BBC World News later moved into the renovated former studio of the BBC News channel.
The channel is transmitted by Red Bee Media from their network centre at the Broadcast Centre within the BBC Media Village, part of the BBC White City, in White City, West London. All news output originates from studio N8 in the nearby Television Centre. The BBC World News newsroom is part of the BBC's Global News Hub, set up in the summer of 1994. The BBC World News newsroom provides output throughout the day. From 0100–0500, the channel BBC News is based within this studio.
Previously, the channel was broadcast in 4:3, with the news output fitted into a 14:9 frame for both digital and analogue broadcasting, resulting in black bands at the top and bottom of the screen. On 13 January 2009 at 09:57 GMT, BBC World News switched its broadcast to 16:9 format, initially in the European Region through the Astra 1L satellite, and Eutelsat Hot Bird 6 satellite to other broadcast feeds in the Asian region from 20 January 2009.
In October 2011, a high definition feed of BBC World News showed up on Galaxy 13 in the United States. Also in September 2012, BBC World News has also launched a HD feed in the Asia Pacific Region on Intelsat 19 at 166.0°E. The channel is speculated for launch in high definition in 2012.
