Well... I’m in the “delightful” position of agreeing with the good Mr. Savage [again]! As a marketer disposed by the consumer electronics industry, I can report

What’s more depressing? ...Radio revenues or “HD Radio” sales? ...I'm sure the the iNiquity apologists are ready with their rehearsed script!
