His daily show now attracts a record 9.5m listeners a week, according to the figures from industry body Rajar.
BBC 6 Music has boosted its audience by 50% to more than 1m listeners a week after coming under threat of closure.

The BBC's media correspondent Torin Douglas says radio is booming, with BBC and commercial radio gaining listeners.
Figures for the Chris Evans show, which is on air for half an hour longer each day than Sir Terry's programme, are the highest audience for any radio show since 1999 when the current system began.

BBC Radio 4's audience rose to more than 10 million, with farming soap The Archers having a record 4.9 million listeners a week and the Today programme 6.4 million.

The pair have just won a Sony award for best entertainment show.
Digital radio also grew, with almost a quarter of all listeners using digital receivers.
