The service places emphasis on rolling news, including the latest breaking news. Sky News also hosts localised versions of the channel in Australia and in New Zealand, as well as their previously operated version in Ireland. Sky News is also offered in an international version without the British adverts under the name Sky News International available in Europe and Asia.
Based at a news centre in London, Sky News started broadcasting on 5 February 1989 as part of the then four-channel Sky Television service. Sky News provides an hourly news radio service to multiple radio networks in the UK and Ireland. The channel currently has seven UK bases each with their own correspondents, and the channel can also call upon a wide range of resources and global bureaux provided by its parent company News Corporation such as reporters from Fox News Channel and Fox Business Network (its sister news and business channels).
Sky News has built its schedule around the main anchors with appointment to view broadcasts regularly being supplemented by landmark broadcasts. Although most of its programmes feature one main presenter, when major breaking news reaches the channel it has recently started to revert to the old double-headed style with two presenters anchoring. Sky News is known for its innovations in news broadcasting and regularly wins awards for this and also for its broadcasting in general.
Sky News has started to revamp its graphics almost every year, with the latest revamp unveiled on 6 May 2010.
In late December 2008, Sky News began broadcasting from Studio B at Sky News centre, while work on the main newsroom was being carried out. On 4 February 2009 at 6am broadcasting resumed from the revamped newsroom. This coincided with the channel's 20th anniversary on 5 February 2009.
From 30 March 2010, Sky News again began broadcasting from Studio B as the final preparations took place for the launch of Sky News HD. Broadcasting returned to the main newsroom at 9pm on 6 May 2010, for the launch of Sky News HD and the results of the 2010 UK general election.
