Key to the Missing was a TV series which aired on Fridays at 7pm EST on the DuMont Television Network from 4 July 1948 to 23 September 1949. Each 30-minute episode was hosted by Archdale Jones. The series interviewed people looking for long-lost friends and relatives. The series was typical of TV programming of the time, when the major TV networks were trying out various untested concepts and ideas. Although short-lived, the basic concept has been re-used many times since, usually by independent TV stations and small TV networks. Where Are They Now, the radio program on which the series was based claimed a 68 percent success rate.
