Princess Diana's 1995 interview and discussion of her failed marriage to Prince Charles has been named as the most memorable moment on television.
During the Panorama interview with Martin Bashir the princess said that she would like to be the "Queen of people's hearts" and claimed that there were "three of us in this marriage" herself, Charles and the then Camilla Parker Bowles.
The poll of 3,000 TV viewers by UKTV Gold placed David Frost's post-Watergate interview with Richard Nixon in 1977 in second place and legendary footballer George Best's drunken appearance on Terry Wogan's chat show in third.
Other interviews which made it into the top ten include Jeremy Packman's persistent attempt to get the then home secretary Michael Howard to answer a question about a prison governor and the Sex Pistols swearing on the Today show with Bill Grundy.
James Newton, head of UKTV Gold, said: "When it comes to TV interviews you can always expect the unexpected - that's why some of these gems are still remembered decades after broadcast."
