RTÉ Radio 1's Morning Ireland is the most-listened to show in the country, and has increased its listenership by 1,000 to 449,000 in the latest figures from the Joint National Listenership Research Survey (JNLR).
This 1,000-listener increase has occurred since the last quarterly figures (known as a 'book') were released; Morning Ireland is up 8,000 listeners year-on-year.
Meanwhile, Today with Sean O'Rourke is listened to by 327,000 people daily, an increase of 6,000 people on the previous year.
O'Rourke took over the presentation of the show last year from the previous presenter Pat Kenny.
Commenting on the figures released today, Managing Director of RTE Radio Jim Jennings said: "This is a very encouraging book for RTÉ Radio and RTÉ Radio 1 in particular, with the station increasing its listenership. For Sean O'Rourke to increase his listenership year-on-year is a remarkable achievement given the amount of changes in the radio market this year.
"2fm also had a very good book with an increase in its audience, and with a new schedule about to launch we feel that there are exciting times ahead for the station. RTÉ lyric fm also had a great book with the station increasing both its daily reach and market share and Marty Whelan increasing his audience to over 40,000."
RTÉ Radio scored 18 of the top 20 programmes among adults 15+, with 1,859,999 (52%) listening every week.
Tom McGuire, Head of Radio 1, said: "These JNLR results are indicative of the 'strength in depth' of RTÉ Radio 1. Today with Sean O'Rourke has 6,000 more listeners than this time last year and every weekend morning the majority of the national radio audience is tuning in to The Marian Finucane Show, while in the afternoons more than 10,000 new listeners are choosing Saturday and Sunday Sport. This truly makes Radio 1 the 'go to' station for news, currents affairs, sport and entertainment and the arts every day."
