BBC Radio "Word of Mouth"

Chris Ledgard examines how trademark law can control the language of
the Olympic games.

As the 100-day countdown to the Olympics begins, Chris Ledgard
examines how trademark law can control the language of the games, and
asks if word use can ever be effectively contained and controlled. He
meets historians charting usage of the term "olympic" over centuries;
talks to comedy producer Jon Plowman about the BBC mockumentary
"Twenty Twelve", and discovers that one American university wants some
words banned altogether.
