Sub-regions
TWW ran the first ever dual franchise. As a result of serving both the West of England and South Wales, the company ran a dual service. The company could either broadcast programmes to South Wales from their Pontcanna headquarters in Cardiff, to the West of England from the studios in Bristol, or to both regions in the so-called General Service.
