Sir David Paradine Frost was a British television host, journalist, comedian and writer. He rose to prominence during the satire boom in the United Kingdom when he was chosen to host the satirical programme That Was the Week That Was in 1962. His success on this show led to work as a host on American television. He became known for his television interviews with senior political figures, among them the Nixon interviews with US president Richard Nixon in 1977 which were adapted into a stage play and film. Frost interviewed all eight British prime ministers serving from 1964 to 2016, from Alec Douglas-Home to David Cameron, and all eight American presidents in office from 1969 to 2008, from Lyndon B. Johnson to George W. Bush.

That Was the Week That Was, informally TWTWTW or TW3, was a satirical television comedy programme that aired on BBC Television in 1962 and 1963. It was devised, produced, and directed by Ned Sherrin and Jack Duncan, and presented by David Frost.
