Brand's radio career began in early 2002, when he hosted a Sunday afternoon show with Matt Morgan on London's Indie Rock station Xfm.
Brand was fired from the job after reading pornographic material live on-air.
In 2005, Brand co-hosted three one-off shows on BBC Radio 6 Music with Karl Pilkington.
Brand then co-hosted The Russell Brand Show beginning in April 2006 on BBC Radio 6 Music.
In November 2006, the show transferred to BBC Radio 2 and aired on Saturdays from 9–11 pm.
The show regularly drew about 400,000 listeners.
In an episode of the show broadcast on 18 October 2008, Brand and fellow Radio 2 DJ Jonathan Ross made a series of phone calls to actor Andrew Sachs in which Brand alleged on air that he had had sex with Sachs' granddaughter.
Sunday tabloid The Mail on Sunday broke the story and regarded the phone calls as obscene.
Both presenters were later suspended by the BBC because of the incident, and Brand resigned from his show.
The BBC was later fined £150,000 by Ofcom, Britain's broadcast regulator for airing the calls.

Brand returned to radio when he and Noel Gallagher hosted a one-off football talk show on 19 April 2009 for Talksport.
Brand returned to Talksport on 9 October 2010, with a Saturday night show that lasted 20 weeks.
The show featured clips and back-stage recordings from his Booky Wook 2 promotional tour.
Brand was joined by a host of guests, including Noel Gallagher and Jonathan Ross.
