This Is Your Life is an American reality documentary series broadcast on NBC radio from 1948 to 1952, and on NBC television from 1952 to 1961. It was originally hosted by its creator and producer Ralph Edwards. In the program, the host would surprise guests and then take them through a retrospective of their lives in front of an audience, including appearances by colleagues, friends, and family.
Edwards revived the show in 1971–1972, and Joseph Campanella hosted a version in 1983. Edwards returned for some specials in the late 1980s, before his death in 2005.
