“Starting next week, when Bob Edwards, the longtime host of National Public Radio’s ‘Morning Edition,’ returns to the radio, he will be heard not over the air on the FM band, but on the $10-a-month XM Satellite Radio service… But for most of the public radio establishment, Edwards’s new gig is a harsh reminder that the future of public radio is very much in flux. If listeners prove willing to pay for satellite radio, much as viewers decided a generation ago to shell out for cable TV, then NPR and other programming providers will be sorely tempted to follow the money.”
