Blue Peter is a British children's television programme, currently shown live on the CBBC television channel. A significant part of British culture, it first aired in 1958 and is the longest-running children's TV show in the world. Although the show has a nautical title and theme, it is a magazine/entertainment show containing viewer and presenter challenges, as well as the famous arts and crafts "makes".During its history there have been many presenters, often consisting of two women and two men at a time. The current presenters are Barney Harwood, Lindsey Russell and Radzi Chinyanganya. The show is produced mainly in a television studio, but there is also a garden, often referred to as the Blue Peter Garden, used during the summer months or for outdoor activities. The programme has always featured a number of pets; currently a tortoise called Shelly makes appearances from time to time.
