Over 1.6 million people tuned in over the course of Ryan Tubridy's debut as host of 'The Late Late Show' on Friday night.
An average of 927,000 people watched the two-hour show and speaking about the ratings, Tubridy said: “I’m thrilled with the figures and grateful to all the people who tuned into our first show.
"These figures are a testament to the hard work behind the scenes and I want to thank everyone involved for making our first show such a great success.”
His first guest was An Taoiseach, Mr Brian Cowen, during which the average audience share peaked at over one million viewers.
Other guests included Brian McFadden, Joan Collins, Academy award nominee Saoirse Ronan, Niall and Gillian Quinn and performances from both Sharon Corr and David Gray, as well as The Late Late Show Band and the RTÉ Concert Orchestra.
Commenting on the show, Steve Carson, Director of Programmes, RTÉ TV, said: “Within the first half hour of The Late Late Show on Friday night, and despite the prowess and skills of the two previous hosts, Ryan made it his own.
"It’s extremely gratifying that the audience not only tuned in but stayed with two hours of prime time broadcasting in such numbers. It’s a credit to Ryan; to his performance, skills and consummate broadcasting ability and to the team who produced a classic and very well-judged Late Late Show.”
Over 16,000 individuals logged on to the RTÉ Player (www.rte.ie/player) to view Friday night’s Late Late Show, where it will be available until Friday 25 September.
