Hulk Hogan is, perhaps, the biggest name in the history of professional wrestling. He’s won multiple world champions while in the then-WWE and WCW and he’s a crossover star. Even non-wrestling fans know the name, Hulk Hogan.
So, why is he blacklisted from WWE? Well, he’s been persona non grata several times. When Hogan jumped to WCW in 1994, WWE would not mention him on TV unless it was a burial on commentary or a parody skit to take a shot at him. Hogan and WWE got back on good terms after WCW was purchased by Vince McMahon and Hogan was welcomed back into the fold in 2002 for a revival of the NWO.
Hogan would later jump to TNA Wrestling in 2009 and, for a short time, tried to compete with Vince McMahon on Monday nights. Hogan would eventually leave TNA and rejoined WWE in 2014 as an ambassador for the company but that was short-lived because tapes of Hogan using racial slurs surfaced via the National Enquirer in July 2015. WWE immediately took action and released Hogan from his contract and his name has not been mentioned since then.
He may be blacklisted now but I’m sure Hogan and WWE will work things out in the near future.
