Moyles provided a 39% boost in listeners for Radio X and gave the station its best breakfast show figures in London in almost a decade.

A typical half-hour segment contained fifteen to twenty minutes of chat, discussing the team members' lives, Radio 1's features, music or popular culture.

There were regular celebrity guest interviews usually between 08:00 and 09:00, with the occasional live music performance and frequent first exclusive plays of new single releases.

Other former regular competitions hosted included Viaduct (named by Simon Mayo when asked for a suggestion about what to call the quiz when Moyles stood in for Zoe Ball on the breakfast show).

Mills used most of his own features from his afternoon slot, and was joined on air by radio personalities Rebecca Huxtable, Mark Chapman and Chris Stark.

When only Moyles was away, Vernon Kay or Sara Cox would present in his place, and stay with the usual format of the show.

On 28 February 2011, it was announced that Moyles and David Vitty would attempt to beat the record for the longest continuous Radio 1 show in aid of Comic Relief.

[11][12] On Friday 18 March 2011 at 08:30, Moyles and Comedy Dave broke the Guinness World Record for the 'Longest Marathon Radio DJ (team)' and by the end of the show (at 10:00), they had hit the 51 and a half hour mark.

During the attempt, the duo were joined by many celebrity guests, including Paul O'Grady, Phillip Schofield, The Wanted, Chipmunk, Jimmy Carr, Craig David, Katy Perry and Ricky Gervais.

[14] The grand total has since increased to £2,821,831 and with an audience of 2.84 Million, the event was the most popular live BBC Red Button radio feature ever.

On 18 November 2011, their record was broken by a breakfast show on the German station 98.8 KISS FM Berlin, when presenters Nora Neise and Tolga Akar were on air for 73 hours.
