No, you can blame the government for sitting on the merger for so long to bleed Sirius dry.
Howard is 60% of the Sirius audience. He isn't going anywhere. Oprah and Martha Stewart, on the other hand, are as good as gone, IMO. No return on those investments at all.
Whoever said Sirius won't email you back is wrong. When Bubba was going through his contract BS. I called Tim Sabean and got a personal return phone call from him.
They won't go silent, but I can't see how they can survive the current takeover attempt from EchoStar (Dish). If Clearchannel (or whomever- CBS, Cox Media, etc) was smart, they would buy Sirius tomorrow and make all their top radio stations have a national presence.
