One day in the life of television is a documentary that was broadcast on ITV on 1 November 1989. Filmed by over fifty crews exactly one year earlier, it was a huge behind-the-scenes look at a wide range of activities involved in the production, reception and marketing of British television. The project was organised by the British Film Institute and produced and directed for television by Peter Kosminsky.

A book by Sean Day-Lewis was published to accompany the documentary. It contained the thoughts of people throughout Britain, including industry professionals, who recorded their feelings and experiences of television viewing on 1 November 1988, the day that the documentary was filmed.
