The BBC News at One is the afternoon news bulletin from the BBC. Produced by BBC News, the programme is broadcast on BBC One and the BBC News channel every weekday at 1:00pm. The programme is usually presented by Sian Williams every Monday, and Sophie Raworth from Tuesday to Friday.
The BBC News at One achieved an average reach of 2.7 million viewers per bulletin in 2007, making it the most watched programme on UK daytime television.
The One O'Clock News launched on 27 October 1986 together with the daytime television service on BBC One serving as a replacement to the BBC News After Noon programme. Martyn Lewis, who had joined the BBC from rival ITN, was the original presenter.
A unified look across BBC news output was introduced in April 1993, and the News at One adopted this look, though still kept some of its individuality, such as a reworked version of the theme music.
A new look across all of BBC News television output on 10 May 1999 meant that for the first time all the main bulletins on BBC One had the same look, the only exception being the title of the programme. At this time Anna Ford took over as the main presenter of the bulletin, staying until her retirement from news reading in April 2006.
On 22 January 2007 the programme titles were relaunched, along with the rest of the BBC television output, to give an identical series of titles across news programming on all BBC channels.
On 4 February 2008, the programme temporarily moved studios, from N6 to N8 (the former BBC News 24 studio), as part of restructuring across BBC News. On 21 April 2008 the programme underwent a graphical refresh and returned to the refurbished N6 as well as changing its name to the BBC News at One.
On 5 November 2010, during the National Union of Journalists strike action, former Sky News and GMTV presenter Emma Crosby presented the programme whilst the regular presenters were absent. Further strike dates occurred on 15 July 2011 and 1 August 2011. Gavin Grey presented both of these days in addition to BBC News Channel.
On 18 March 2013, the programme moved to Broadcasting House, along with the BBC News channel and the other BBC One bulletins, and began broadcasting in high-definition. The programme was the first to be broadcast from the new studio.

One O'Clock News Hour 
The BBC News at One has been shown on the BBC News channel since April 2006, making up the first half hour of the BBC News at One. Significant differences can be seen between the two halves of the programme, as the second half is presented by the News Channel presenters Matthew Amroliwala and Jane Hill. During the headlines and 'coming up' section, BBC One viewers see a preview of the stories to come from their region, while BBC News viewers see sports headlines. Between 12:45 and 13:30 BBC News has a service providing in-vision British Sign Language for those viewers with hearing difficulties.
