Up All Night is a late night phone-in programme broadcast on the national news/sport station BBC Radio 5 Live in the United Kingdom, usually on air between 1and 5am every night. It is also broadcast on most of the BBC's local radio frequencies across England as well as on Radio Scotland, Radio Wales and Radio Ulster. The Washington Post once described the show, in its previous guise as a news and current affairs show, as probably the best night-time radio show in the world. History Originally a news and current affairs show with occasional topical phone-ins, Up All Night was broadcast continuously from Radio 5 Live's launch on the 28 March 1994 until 27 March 2020. The show originally lasted three hours and was extended to four from 1998. One of the show's two main presenters, Rhod Sharp, had proposed the idea of an all-night radio show for the new station that made use of the BBC's correspondents from all over the world. He continued to present several shows each week (Monday to Wednesday) until March 2020, when he stepped down. Dotun Adebayo was the show's second main presenter, hosting the show from Friday night to Sunday night. Other presenters included Richard Dallyn, Dalya Raphael and Russell Fuller. Up All Night used guest presenters regularly on Thursday nights (Friday mornings) from 3 November 2017. The first guest was Richard Foster, then Tom Green, and Rachael Bland. Following the departure of Sharp in March 2020, coinciding with the COVID-19 lockdown, the programme was temporarily replaced by a nightly phone-in show from BBC Radio London, syndicated across BBC local radio stations. Adebayo moved to the weeknight slot and some popular features, such as the World Football Phone-In, were carried over. On 6 July 2020, the programme returned to Five Live with a heavily revised format. Other than a short 10 to 15 minute interlude at the beginning of the show, it is almost entirely given over to the public phone-in format. Some features, such as the World Football Phone-In, have been carried over, but the regular updates on news stories around the world, including regular conversations with BBC overseas correspondents, have been largely abandoned. Broadcast locations Originally broadcast from studios at Broadcasting House, London and then from studios at Television Centre, the show's production, along with the rest of the BBC Radio 5 Live scheduled programmes, moved to MediaCityUK, Salford, Greater Manchester
