Masterpiece Theatre is a Long-Running primetime series on PBS that usually showcases BBC productions (Channel 4 and ITV material are occasionally featured). The series premiered in 1971 and was originally hosted by Alistair Cooke, but has had a number of presenters since his retirement in 1992. Its well-known classical title theme is Jean-Joseph Mouret's Rondeau. Adaptations for TV by the BBC of Shakespeare and other classic works are very often syndicated to appear on Masterpiece in the US, usually through WGBH-Television in Boston, often in multiple parts.
