In the autumn, the recently returned Ray D'Arcy will take up RTÉ's Saturday night chat show mantle, but meanwhile, Miriam O'Callaghan returns for another summer run of entertainment and chat.
Believe it or not, this is the 11th series of Miriam's show, which sees the Prime Time presenter switch from current affairs to light entertainment. The programme, which runs for eight weeks across the summer, mixes live music, human interest stories, and interviews with well-known faces from the worlds of showbiz, sport, politics and the arts.
Previous guests who joined Miriam on the couch include Colin Farrell, Kate Beckinsale, Brendan Gleeson and Daniel Radcliffe and - while the line up had not been revealed at the time of going to press - there are some equally big names from both Ireland and abroad promised for this new season.
After Miriam's ground-breaking interview with Health Minister Leo Varadkar on RTÉ radio earlier this year, no doubt viewers will be eager to see what probing questions the broadcaster will ask.

Exiled by the British to the remote Atlantic island of Saint Helena, the great man spent his final years fulminating bitterly about what might have been.

An Irish original
This new documentary charts the truly extraordinary career of Tony Ryan, a CIE man's son from Limerick who created one of the world's biggest airlines. Tony was just 18 when his father died: he grew up fascinated by travel, and joined Aer Lingus as a young man. After founding Guinness Peat Aviation, he set up Ryanair in 1985, a venture that began humbly and might have seemed foolish at the time, but has proved a rather large success.

Finally, it's back
Season two of the acclaimed HBO crime drama kicks off this week. Gone are Matthew McConaughey and Woody Harrelson's bickering detective team, and in their place is Colin Farrell, playing Californian police detective Ray Velcoro. The police department he works for is hopelessly corrupt and Ray is in thrall to a local gangster. Rachel McAdams, Taylor Kitsch and Vince Vaughn co-star in a drama that may just become addictive.
