Tannoy

[2] The company name was changed to Tannoy in 1928 and a small factory was opened in Dalton Road, West Norwood, later moving to Canterbury Grove.

[3] Tannoy speakers were also supplied to factories around Britain to relay the BBC's motivational radio series Music While You Work,[4] and to Butlins and Pontins holiday camps following the war - where they were famously used to waken guests with the words "Good morning, campers!".

Following the Music Group acquisition, it was suggested that the Coatbridge facility would be closed and all related activities would be relocated to Manchester, England.

The brand was trademarked by 10 March 1932, on which date the Tulsemere Manufacturing Company formally registered as Guy R. Fountain Limited.

To preserve its trademark, it often notifies publications not to use its trade name without a capital letter, or as a generic term for a PA system.

Actor Cyril Ritchard and three young women listen to the Tannoy public address system in 1948.
