The Late Late Show is the world's longest-running chat show and officially the flagship television programme of Irish broadcasting company Radio Telefís Éireann (RTÉ). The show, hosted by Pat Kenny, is broadcast live for two hours in front of a studio audience at 21:30 on Friday nights between September and May. It is broadcast from Studio 4 in RTÉ's headquarters, a studio specifically adapted in 1995 to cater for this flagship production, and Kenny Live. The show was previously broadcast on Saturday nights. At present it is sponsored by Halifax.
The Late Late Show was first broadcast on Friday, 6 July 1962 at 23:20. Since then, its format has remained largely the same, with music, chat, and audience involvement in debates on topical issues. The show's rapid rise to popularity led it to top the ratings consistently on RTÉ for forty years. Some sociologists have credited it with influencing Irish attitudes towards many issues, and directing social change in Ireland to construct current Irish societal norms.
