BT, WHICH HAS LONG FROWNED on unofficial ads in its telephone kiosks [‘French chest with removable drawers, phone ...’], has finally decided to go legit and accept ads suitable for the entire family. The company plans to sell ad space in 50,000 kiosks across the country, kicking-off with a pilot scheme for soft drinks brand Tango in 3,000 booths in the Meridian TV area. Branded Phonesites, the venture will offer national or regional coverage, with illuminated displays - Phonelights - also available. Enthused BT’s head of marketing Steve Davis: ‘Advertising in kiosks really works.’ [No truth in the rumour that Davis has approached a Ms Sadie Flagelle of Soho to endorse his claim.]
