The first series was intended to be eleven episodes, purely acting as links between the usual staple fillers of old films and cartoons that ATV would transmit on Saturday mornings. Presented by Chris Tarrant and John Asher from merely a desk in a continuity studio, the pair had to rely on ad-libs and jokes sent in by viewers. Within a few weeks, the show was moved to studio 3 at ATV Centre (a studio usually reserved for amongst other programmes, the news magazine programme, "ATV Today") from which Tiswas was produced for the majority of its run.
