British TV shows pulled after a single episode across five decades

A number of British television programmes across five decades have been pulled from schedules after airing a single episode, with cancellations driven by poor reception, scheduling changes and, in at least one case, a controversy over a contestant. The titles include a 1975 BBC sitcom, late-night programming on a now-defunct interactive channel in 2007, several Channel 4 commissions in the 2010s and 2020s, a Sky History competition in 2020 and a Channel 5 science series in 2025.

One of the earliest examples was a BBC sitcom called The Melting Pot, written by and starring Spike Milligan. A one-off pilot was broadcast on BBC1 in June 1975. Five further episodes had been commissioned and produced but were not transmitted. The programme drew criticism for Milligan performing in blackface and for its depiction of an illegal immigrant character, and the remaining episodes were withheld from broadcast.

The Debbie King Show, a late-night programme on the ITV Play channel, aired in the early hours of March 5 into March 6, 2007. That broadcast coincided with the final day of the channel, and no further episodes were transmitted after the channel closed.
