Why not? I'm sorry, but the WWE has literally no excuse. They have the money, the exposure, the publicity, the talent, the platform, the audiences and LOADS of TV time to make someone into a mega star again.
If they could do it in the 90's, why can't they do it now? Because they no longer know how to. Their writers aren't as good, their vision isn't as good, their drive isn't as good and they focus more on their corporate identity and branding than they do on creating stars and a wonderful experience for us.
TNA on the other hand has managed to create some respectable names in the wrestling industry with less than half of WWE's exposure, a mere fraction of WWE's finances and an even smaller cut of the market and their brand awareness. They built their own guys and made them into something. In fact, they continue to do so with people like Austin Aries and Magnus.
Aries, Magnus, Bobby Roode, James Storm, Kazarian, Daniels, AJ Styles, Samoa Joe, among others have all been a vital part of TNA's main events and programming in general and have consistently contributed to the product. Meanwhile, WWE's been betting their money on the same two people for the last twelve years. John Cena, and Randy Orton.
Guys like Punk, Bryan, Ziggler, Miz and so forth have only had short stints at the top and WWE has failed to capitalize on whatever appeal they had. I already told you why this happens.
Instead, they keep coming back to The Rock, to Batista, to Brock Lesnar and a slew of other former stars like Hogan and whoever else they can dig up, to sell their WrestleMania. With so much focus on that kind of business, there's less time for the other talent and they end up eating their dust. So much, that some of them straight up quit, like CM Punk. Don't think for a second his frustrations aren't shared among the locker-room. He's just the only one that is financially stable enough to leave, and also crazy.
Say whatever you want about TNA, but in the last few years they have slowly transition from a company that focuses more on established talent from other companies, to a company that focuses more on building its own guys, pushing them to the Main Event while establishing others to take their place and continue the circulation of talent.
It took TNA 2 years to build Aries, Roode, Storm, Magnus, and even Bully Ray into legitimate Main Event stars. What's WWE been doing for the last 12? Figuring out who's coming back for WrestleMania, that's what.
TNA simply can't build a mega star because they lack the exposure to their product required for that to happen, they can just have a guy who's really over in front of 4000 people. WWE, however, does. Big arenas, 2-3 million people watching every week - no excuse.
You're missing the point I made about WWE not being able to create a megastar recently. It's not about having resources, money, etc. It's more about timing, era, and the sort of available performers. Austin and Rock weren't just product of some "creative scriptwriters" even if Vince Russo gave them a bunch of catchphrases. If you think 1998 had a superb and motivated creative team unlike today, why didn't Val Venis, The Godfather, Mark Henry, Viscera, Gangrel, all became superstars or megastars?
Inference is that in any age/era, there can only be N number of megastars based on charisma, natural aptitude, etc. If talent and stardom were so easy to replicate, then why aren't so many 6-ft-2 and 6-ft-4'ers becoming Hollywood Megastars like the Rock? The answer is obvious. It's not creative that creates a megastar.
Look at Brock Lesnar. Sure, WWE invested in him, dubbed him as the next big thing and all, but without his natural aptitude, his amazing in-ring ability crafted and created by years of his amateur wrestling background, we wouldn't have gotten Brock Lesnar that was never quite the Megastar but could've become(had he not left in 2004). Case in point- Mason Ryan.
You can't just take a tall beefed up musclehead and give him a name and gimmick and expect him to be a blockbuster success or create a Wrestlemania classic. If that were true, by now we'd have seen the advent of dozens of Muscle-heads who'd all have been as intriguing as Lesnar,Cena, etc .
TNA hasn't even been close in creating a household name. I don't consider Austin Aries, Samoa Joe, or Magnus a "household name". AJ Styles, yes. But he's gone now.
And WWE hasn't been "figuring out who's coming back for Wrestlemania" for the last 12 years. That's a gross overestimation of time by you.
As far back as 2010, WWE main events all comprised home-grown talent from the 90s and Ruthless Agression Era including John Cena, Edge, Batista, Undertaker, HHH ,Randy Orton.
It was only from 2011 that this trend of bringing up stars from the past to sell/sustain Wrestlemania has begun. So yeah, I'll admit to that that the WWE has never relied on CM Punk or others to be in main events or sell the event on their own but instead brought back The Rock.
And while you bash WWE for bringing The Rock, Brock, or Batista to sell their "biggest ppv of the year", why not consider what TNA has done with Bound for glory? At least WWE brings performers still in their prime and under Age 45.
Bound for Glory's main event in 2010 was Jeff Hardy vs Mr. Anderson vs Kurt Angle- all Ex-WWE stars.
In fact, more than half of the card featured Ex-WCW and Ex-ECW superstars. Was TNA really so desperate that one of the main-event matches on BFG comprised of Stevie Richards and company?
In 2011, TNA did what WWE wouldn't do. Feature 2 very old superstars in one of the main events where Grandpa Hogan faced off against Sting. Seriously, did TNA have to redo it just for the sake of Nostalgia or to have an appearance of Spectacle and Grandeur?
Kurt Angle , again a WWE-created star def Bobby Roode for the Heavyweight title.
BFG 2012 once again had 2 main-events feature Ex-WWE talents in Aces and Eights, and then Jeff hardy def Austin Aries.
It's not just the WWE that'll use "big names" to sell/promote their biggest ppv. TNA has been desperately doing the same, until 2012. I needn't cite any more references.
