The BBC confirmed on 2 June 2010 that Last of the Summer Wine would no longer be produced and the 31st series would be its last. Subsequently, the final episode was broadcast on 29 August 2010. Since its original release, all 295 episodes, comprising thirty-one series—including the pilot and all films and specials—have been released on DVD. Repeats of the show are broadcast in the UK on BBC One, Gold, Yesterday, and Drama. It is also seen in more than 25 countries, including various PBS stations in the United States and on VisionTV in Canada. With the exception of programmes 'rebooted' after long hiatuses, Last of the Summer Wine is the longest-running TV comedy programme in Britain and the longest-running TV sitcom in the world.
