Its flagship programmes are The Big Breakfast with Brendan O'Loughlin and Rebecca Shekleton, The Sound of the City with Barry Dunne, The Big Ride Home with Brian Maher, The Fix with Leanne Hanafin and The Sound of the City at Night with Karl Dawson.

The station broadcasts hourly news (half-hourly at peak times) along with sports, weather and traffic reports.

The station's first broadcast was in 1989, as a rock station called Classic Hits—98FM and quickly overtook rival Capital Radio 104.4 (now FM104), sometimes attributed to the Morning Crew show, originally presented by Pat Courtnay and Elaine Geraghty, and to its evening talk show presented by Fr.

This led to a crisis at 98FM, with the station changing aspects of its programming, starting by dropping Pat and Elaine for the "Dawn Patrol".

In November 2012, the station dropped the Morning Crew title when former Today FM presenter Ray Foley took over the breakfast show replacing Aidan Power and Claire Solan.

It was announced on 22 December 2015 that Ray Foley would cease to present the station's breakfast show.
