Nationwide is an Irish television programme broadcast on RTÉ One every Monday, Wednesday and Friday evening at 19:00, around 35 minutes long. It is currently presented by Anne Cassin and Mary Kennedy. The programme focuses on human interest stories and cultural events across the island of Ireland, generally but not solely outside of Dublin. The show is produced by RTÉ Cork. It, along with Capital D, a programme featuring Dublin, serves a similar purpose to the occasional RTÉ attempts to regionalise news and human interest content in the past, albeit without the increased technology and transmission costs, which would likely require total re-engineering of the country's transmission and cable television networks. Nationwide itself was the sole programme regionalised in recent times, but this has now ceased. Nationwide is the brainchild of Michael Ryan. On 20 December 2011, Anne Cassin was announced as Michael Ryan's replacement as presenter following his retirement.

Fáilte Towers was an RTÉ reality TV show that was broadcast as a one off during August 2008. The concept of the show involves thirteen celebrities running a hotel for sixteen days and nights in order to win money for their designated charities. The show format was not repeated nor was it exported or resold. The name is a play on the BBC sitcom Fawlty Towers: and the word Fáilte meaning "welcome" in Irish. The hotel used in the series is Bellingham Castle in Castlebellingham, County Louth. The show is presented by Aidan Power and Baz Ashmawy and the judges are Bibi Baskin, Dublin restaurateur Derry Clarke and Castle Leslie hotelier Sammy Leslie. Each night the public are invited to vote for the contestant they would like to stay in the show. At the end of the show one of the contestants must "check out". The presenters tell each of the contestants individually if they are "safe" and if so are ordered "back to work". The three remaining contestants are then marched into the Oliver Plunkett Suite to face the judges, one of whom sends one of the contestants back to work before all three cast their votes on which of the remaining two must leave the show. The evicted celebrity is then interviewed by the presenters, with best bits shown as well. Created by Adare Productions, it was available to watch online on the RTÉ Player for up to two weeks after being broadcast. John Creedon won on 17 August.

Know Your Sport is an Irish sports quiz show produced by RTÉ between 8 October 1987 and 1 April 1998. The show was presented by George Hamilton and featured Jimmy Magee and Mary Hogan as scorekeeper.

In 2009 an appeal to re-introduce the show to RTÉ's schedule gathered support on networking website, Facebook.
