Jim Jennings has been appointed the Managing Director of RTÉ Radio following a public competition.
A former Head of RTÉ Radio 1 and Acting Managing Director of RTÉ Radio for the past six months, he has also worked as Executive Producer of The Late Late Show and began his career as a radio researcher in RTÉ.
Commenting, he said: "I'm delighted and honoured to take on the responsibility to lead the radio division, and RTÉ Orchestras, Quartet and Choirs.
"My career in RTÉ began in radio over 25 years ago and radio has always been close to my heart. It's a humbling experience to be taking on such an important role in media in Ireland."
Noel Curran, Director General RTÉ, said: "Jim Jennings has a huge range of editorial and management experience and a keen understanding of the unique position of RTÉ Radio nationally.
"As Head of Radio 1 he saw the station maintain its position as Ireland's most-listened-to radio service, a considerable achievement in a market that grows more competitive by the month.
"His track record of innovation around comedy, current-affairs and music; his public commitment to finding new on-air voices and his willingness to take risks for the audience, mean that it promises to be an exciting road ahead for RTÉ Radio 1, 2fm, lyric fm, Raidió na Gaeltachta and RTÉ's six digital radio services."
