BBC Radio 1 part of a Guinness World Record attempt, in aid of Comic Relief. The pair stayed on air for 52 hours in total setting a new world record for 'Radio DJ Endurance Marathon (Team)’ after already breaking Simon Mayo's 12-year record for Radio 1's Longest Show of 37 hours which he set in 1999, also for Comic Relief. The presenters started on 16 March 2011 and came off air at 10:30am on 18 March 2011. During this Fearne Cotton made a bet with DJ Chris Moyles that if they raise over £2,000,000 she will appear on the show in a swimsuit.
BBC Radio 1 was announced that Nick Grimshaw would leave the Breakfast Show after six years, the second longest run hosting the show in history (only second to Chris Moyles). However, Grimshaw is not leaving the station, but swapping slots with Greg James, who normally hosts the home time show from 4-7pm weekdays. This change took place as of 20 August 2018 for the Radio 1 Breakfast Show (which was then renamed to Radio 1 Breakfast). Nick Grimshaw's show started on 3 September 2018. In June 2018, another series of schedule changes was announced. This sees the BBC Introducing Show with Huw Stephens
