^^^The difference there is that Impact is the only TNA show (Xplosion doesn't count because of it's WEAK syndication) for people to watch. That's the show that going to showcase all of it's top talent & name brand stars. ECW is the "C" level show & WWE has made that clear. When they advertise something important on ECW, people do tune in more than would normally do like when Undertaker showed up to team with Kane. However, a majorty of the ECW advertising on RAW is matches that would be on Heat like Kofi Kingston vs. Shelton Benjamin...there's no appeal there so people won't tune in. That's the main difference there.
