TNA is not stagnating, they are growing.
This is my point - WWE pulled 3.5m viewers while TNA consistently pulls 1.4-1.8m. RAW used to have triple the audience and now they struggle to have double. This isn't a decline in WWE or stagnation from TNA. It is the change in TV audiences. TNA has maintained their ratings since about 2008 while WWE has fallen off a cliff, 5.5m viewers per episode down to 3.5m. Network TV shows get renewed at 2.0 or above while in 2008 anything less than 3.0 was considered a joke. That is a 33% decline.
That 33% is pretty accurate for WWEs' decline since 2008 while with TNAs' stagnation it could be argued TNA has instead grown 33%. That is how I look at it, it makes more sense as 2008 to 2012 is like comparing an Apple to a Lobster, you can't do it.
So - Hogan, Hardy and good booking have led to a rise of 33%. That seems about right.
