Claim: Chris Evans (presenter) hosted a programme.

The One Show is a BBC Television magazine and chat show programme . Broadcast live on BBC One on weekdays at 7pm , it features topical stories and studio guests . It is currently co-hosted by Alex Jones or Angela Scanlon , alongside Matt Baker -LRB- Mondays to Thursdays -RRB- and a guest host on Fridays . Various reporters also assist with subject-specific presenting , both in the studio and on location , or through filmed segments . Originally produced in Birmingham and then in BBC 's Media Village in White City , London , since 2014 the studio is in Broadcasting House , the BBC 's headquarters in London .   Launched with a pilot series in 2006 , leading to a full series from 2007 , it has had various previous permanent and temporary hosts ; the partnership of Jones and Baker began in 2011 , with Chris Evans serving as the first Fridays only host from 2010 until 2015 . Prior to the introduction of Evans , the longest presenting partnership was Adrian Chiles and Christine Bleakley from 2007 to 2010 . Their easy and approachable on-screen chemistry is credited with boosting ratings after an unpromising start , establishing the show as a popular staple of British viewing .   The programme is ordinarily 30 minutes long , although it is occasionally extended to an hour . It runs all year round , apart from a two-week break at Christmas and a four-week summer vacation , with the summer slot filled with a highlights show , The One Show : Best of British , presented by Matt Allwright and Lucy Siegle .   Launching the full series represented a major financial commitment for the BBC and was seen by them as a first test of a wide-ranging restructuring of the BBC 's production arm into a more flexible and creative organisation , with the show seen as potential platform for piloting other programme ideas .
