The Washington Post had a story in their Magazine on January 19 on XM radio and its programming guru - Lee Abrams. Abrams is the guy who gets the credit/blame for formaticizing FM. It's available [link|http://www.washingtonpost.com/ac2/wp-dyn/A57791-2003Jan15|here] at WashTech.
It's a shame that XM seems to have had the life formatted out of it as well (based on my understanding of BP's comments).
Your writeup gives a great view of the tragedy that is FM radio. Thanks.
Cheers,
Scott.
