Tiswas (/ˈtɪzwɒz/; an acronym of "Today Is Saturday: Watch And Smile") was a British children's television series that originally aired on Saturday mornings from 5 January 1974 to 3 April 1982, and was produced for the ITV network by ATV. It was created by ATV continuity announcer Peter Tomlinson (later to become a regular presenter on the show) following a test period in 1973 when he tried out a few competitions and "daft stuff" between the programmes.
