A 40% rise in listeners to BBC digital radio station 6 Music is being largely attributed to host Russell Brand.
Russell Brand is also a familiar face on television
The station now attracts a weekly audience of 400,000, according to industry ratings body Rajar.
"It has been good for digital radio to have a star like Russell presenting on 6 Music. He really is at the top of his form," said controller Lesley Douglas.
Radio 2 has also added listeners, with drivetime host Chris Evans gaining ground after an initial dip.
Ms Douglas said: "I'm really pleased that Chris Evans has fitted in at Radio 2. He's a great personality, a great broadcaster and I always hoped he would appeal to the audience."
