The British Broadcasting Corporation, or BBC, is the world's largest broadcasting corporation. As such, the company, and especially BBC Radio, have had a major influence on the adaptation of Tolkien's works.
 BBC Radio Drama
The "Rep" kept an ensemble cast of 30 to 35 actors, up until the mid-1980's. This cast included young theatre talent, such as Anthony Daniels and William Nighy, and was sometimes expanded with popular names.
