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. The BBC Repertory Company, as it was called at their founding in 1940, kept an ensemble cast of 30-35 actors up until the mid-1980's. These have included Anthony Daniels, Norman Bird and John Moffat. This section of the BBC is now called the National Radio Company or NRC, and has been awarded many times.
