This Is Your Life was a television show hosted by Ralph Edwards, first broadcast in the United States from 1952 to 1961.
The show was exported to several countries, including the United Kingdom, where it was launched in 1955 on the BBC and was presented by Eamonn Andrews (who also ended up being the very first "victim"). It moved to ITV in 1969, and Michael Aspel (himself a "victim" in 1980) became presenter after Andrews died in 1988. It returned to the BBC in 1993, and was axed in 2003.
The format of the show was simple: the host would ambush a celebrity or public figure, present them with a 'red book', and then conduct a biography of them in a television studio.
