CNBC on MSN Money: With more than 1,200 radio stations in the United States reaching more than 100 million listeners a week, Clear Channel Communications is the industry's goliath.. With about one-tenth the audience, Sirius Satellite Radio is the David. And their battle is just beginning.

A rather dull read in my opinion. More interesting is the disclosure at the end of the article: (CNBC is carried on Sirius and its competitor XM Satellite Radio. It holds warrants to buy stock XM Satellite.)
