Sir Michael Terence "Terry" Wogan, KBE, DL (3 August 1938 – 31 January 2016) was an Irish radio and television broadcaster who worked for the BBC in the United Kingdom for most of his career. Before he retired from his BBC Radio 2 weekday breakfast programme Wake Up to Wogan in 2009, it had eight million regular listeners, making him the most listened-to radio broadcaster in Europe. Wogan began his career on the Irish national broadcaster RTÉ in the 1960s.
Wogan was a leading media personality in the UK from the late 1960s and was often referred to as a "national treasure". In addition to his weekday radio show, he was known in the UK for his work for television, including the BBC One chat show Wogan, presenting Children in Need, the game show Blankety Blank and Come Dancing. He was the BBC's commentator for the Eurovision Song Contest from 1971 to 2008 and its host in 1998. From 2010 to 2015 he presented Weekend Wogan, a two-hour Sunday morning show on BBC Radio 2.
Wogan acquired dual British and Irish citizenship in 2005. He was awarded a knighthood in the same year and was thus entitled to use "Sir" in front of his name.
