Long-serving Blue Peter editor Biddy Baxter, who turned the children's show into a television institution, has died at the age of 92. Over more than two decades, she introduced generations of children to the pleasures of sticky-backed plastic, on-screen pets, presenters' adventures and charity appeals - a recipe that stood the test of time. She was also passionate about getting her viewers involved in the programme, long before audience participation became an industry mantra. But during her tenure, which lasted from 1965 to 1988, she also gained a reputation as a formidable figure - a tyrant who fell out with presenters and jealously guarded the Blue Peter brand.
