After working for two years in the BBC corporate centre on projects related to the renewal of the BBC's Royal Charter, in 1993 Bannister was chosen as the new controller for BBC Radio 1, replacing Johnny Beerling who had worked at the station since its inception in 1967. Many of the DJs, producers and other staff at Radio One had grown old with the station, as had the audience. Keen to return the station to its original purpose for "young listeners", Bannister overhauled the staff, resulting in many presenters either resigning or being sacked and replacing them with new presenters. Over the next few years the station lost approximately 5 million listeners.
