After a short spell in a lowly job at the BBC selecting press cuttings for use in programmes, he secured a post as a junior member of the editorial staff of a weekly periodical, Truth, in 1953. Levin became a well-known broadcaster, first on the weekly satirical television show That Was The Week That Was in the early 1960s, then as a panelist on a musical quiz, Face the Music, and finally in three series of travel programmes in the 1980s. He was described by The Times as "the most famous journalist of his day"
