1928 - 1934
Broadcast Twelve Records was a United Kingdom based record label introduced in 1928 to partner the regular "Broadcast" brand records introduced in 1927. The manufacturer of the discs were the Vocalion Gramophone Company and was a subsidiary of the British branch of Vocalion Records.
"Broadcast" discs were 8-inch (later increased to 9-inch) and "Broadcast Twelve" discs were 10-inch 78rpm gramophone records, but with small labels and a fine groove pitch so they would play as long as regular 10- and 12-inch discs respectively.
They ceased production in 1934.
