Postman Pat's first 13-episode series was screened on BBC1 in 1981. John Cunliffe wrote the original treatment and scripts, and it was directed by animator Ivor Wood, who also worked on The Magic Roundabout, The Wombles, Paddington Bear, and The Herbs. Following the success of the first series, four TV specials and a second series of 13 episodes were produced during the 1990s. Here, Pat had a family for the first time. A new version of the series was produced by Cosgrove Hall Films from 2003, which expanded on many aspects of the original series.
