1968: BEHIND THE SCENES in BBC STUDIO ONE | Blue Peter | Classic Children's TV | BBC Archive

Val, John and Peter take viewers on a whistlestop tour behind the scenes of Studio One at BBC Television Centre while simultaneously broadcasting a live episode of Blue Peter.
Studio One is the biggest studio in BBC Television Centre at 10,800 square feet, with huge doors measuring 18 feet high and 14 feet wide.
The studio ceiling contains 168 scenery hoists and 240 electric lighting hoists. Up to 500 individual lamps can be installed and these are all operated from the lighting control room.
The studio has six floor cameras and a Transatlantic crane called 'Big Bill', which can raise a camera and camera person up to 20 feet above the ground.
The pictures from all of these cameras go through to the production control room, where the studio director, with assistance from the vision mixer, chooses which pictures are seen by the viewers at home.
Presented by Valerie Singleton, John Noakes and Peter Purves.
Originally broadcast 25 March, 1968.
Blue Peter is still going strong, with new editions of the show broadcast live on CBBC and BBC iPlayer every Friday at 5pm: www.bbc.co.uk/...
