JimmyJames said:Roger_That, actually XM's "Decades" channels were both critical successes AND heavily listened to channels - then Sirius cost themselves a lot of goodwill by making them more FM style. So deeper oldies channels were working on satellite radio.
"Critical successes" tend not to make money.
The decades channels increased their usage per the satellite ratings when they tightened up from the "anything that was recored in the decade" policy.
