Blue Peter is a British children's television programme, shown on the CBBC television channel. 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, its current format takes the form of a magazine/entertainment show containing viewer and presenter challenges, as well as the famous arts and crafts "makes".
