The incoming host of The Late Late Show gained an extra 18,000 listeners to his Radio One show, taking his morning show audience to 333,000.
"The huge increase in The Tubridy Show listenership figures tops off an extraordinary week in my broadcasting life," he said.
"All credit must be given to The Tubridy Show team who come up with an eclectic mix of items on a daily basis.
"I'm very grateful to all of our regular listeners and, of course, welcome all the new members of our club."
The latest JNLR/TNS mrbi listenership figures indicate that talk show radio hosts were the bigger winners -- with outgoing Late Late Show host, Pat Kenny also adding 18,000 new listeners to his daily radio show on RTE Radio One giving him a total of 323,000.
At Newstalk's 106-108fm, newcomer Tom Dunne grew his audience by a huge 41pc, making a "successful transition from music to talk radio" and his station claims he is winning listeners from RTE's Gerry Ryan.
Another big winner was Joe Duffy's Liveline, up 21,000 to 413,000 -- the rise followed a 14,000 surge in his audience last February and brings the Dubliner's listenership to an all-time high.
However, the figures also indicate that Gerry Ryan, seen by many as a contender for The Late Late Show job, was one of the big losers, with the audience for his 2fm show down 11,000 to 306,000.
The new figures demonstrate a huge surge in the popularity of news and current affairs show, with listeners seemingly hungry for news on the nation's gloomy economic prospects.
The surging interest helped push overall radio listenership to its highest level since 2003, with 86pc of the population tuning in each day. RTE's Morning Ireland remains Ireland's most popular radio show with 450,000 listeners, with increasing audiences tuning into news and current affairs programmes, including the News at One, Marian Finucane and Drivetime.
The overall radio market has increased with more than three million people listening on weekdays, more than 2.5 million on Saturdays and more than 2.3 million on Sundays, RTE said.
RTE's The News at One, with Sean O'Rourke, was up 5pc, with 16,000 extra listeners, to give a total of 351,000.
Today FM's Ray D'Arcy was one of the few losers of the day, dropping 7,000 listeners.
"I wouldn't call it a concern, but we are looking at it," said Today FM boss Willie O'Reilly.
