Sigh......they can put on an entertaining product to their fans (that's great) but it wouldn't make them any more money than what they are currently raking in right now, because they're aren't big enough in the mainstream market. Therefore sooner or later, there won't be a TNA for YOU to enjoy. There's only a few who actually enjoy TNA, and that's not enough for them to keep the company running. Like I said, they're in the same phase as ECW, when they were about to fold.
The first step to gaining a strong audience is exposure/marketing, not putting on a good product. If you advertise your product to the market, then people will gain interests. Then, you can start working on putting an entertaining product. How do you think the WWE is as big as it is today? When Vince took over, he brought in Hogan, marketed him as an cult hero, and the rest is history.
I can never see TNA do this, for two reasons: one, they don't have the support from their owners and two, their president (Dixie) has no background on how to run a wrestle business.
