After announcing on September 7 that he was stepping down from the Wake Up To Wogan show, Wogan gave a final, emotional broadcast on December 18. During the three-month period, his 8.1m listening figures matched his previous record gained in Q1 2008.
The veteran broadcaster will start his new two-hour show, Weekend Wogan, on February 14 at 11am live from the 350-seat Radio Theatre in BBC Broadcasting House.
BBC Audio & Music director Tim Davie said: "Terry is a legendary broadcaster and these figures show his popularity has never been higher.
"I'm now looking forward to tuning in to his new show later this month, along with all the TOGs. I'm also pleased to see growth amongst our digital-only stations and robust figures across the BBC Radio portfolio."
According to data released today by RAJAR (Radio Joint Audience Research), Wogan also closed his breakfast career with a clear lead over rival Chris Moyles as just 7.24m listeners turned in to his Radio 1 show, up from 7.04 million the previous quarter.
