BBC Television Service

(2 November 1936-1 September 1939, 7 June 1945-2 December 1953)
Logo: On a black background, we see "B.B.C.". Below it is "TELEVISION SERVICE". Under that is the name of the system being used, either the Baird or the Marconi-E.M.I.

Trivia: The "Bat Wings" ident was designed by, a British graphics designer.

Variants: There were many variants including wave-shaped colour bars in different shades of white and black, along with one that consists of a "compass" with some bat wing-like shapes on the sides in various shades of grey with "BBC" on the top and bottom, all on a grey BG. In 1987, BBC made a classics movie and one clip has this logo, but instead of the Baird or the Marconi-EMI system, the Dolby system is credited.

Technique: None.

Music/Sounds: None, but may contain music and/or a continuity announcer.

Availability: Extinct on TV; these usually appeared at the start of BBC's broadcasts around this time.
