#3 Hulk Hogan vs. Vince McMahon
The jury might still be out on who has had the greatest individual impact on the wrestling business, but two names that are commonly mentioned as part of this conversation are Hulk Hogan and Vince McMahon.
Throughout the 80s, the WWF managed to take professional wrestling to unprecedented levels of acclaim worldwide and a huge part of that was Vince McMahon's booking of the Hulk Hogan character.
While the 80s was a period of perfect harmony between the two, the 90s was an entirely different affair. First came the lawsuits in which Vince McMahon was put on trial for allegedly giving steroids to his wrestlers. During the trial, Hogan admitted to taking steroids to help his performance but stopped short of blaming McMahon directly.
Then came his very public signing with Vince's main rival WCW. Hogan helped the southern promotion reach a level surpassing that of WWF in the mid-90s which threatened to bury McMahon's company for good. When WWF finally conquered Ted Turner and Eric Bishoff in 2001, many were wondering whether Hogan would be coming home to the company he helped build.
It would take a while after the initial purchase of WCW for Hogan to arrive back on WWF television, but it wouldn't be long before a rivalry would form between the Hulkster and his former boss. The feud basically wrote itself considering the amount of history between the two, but with Vince's overacting and Hogan's huge amount of experience on the mic, this turned into a signature programme for the WWF in the lead up to Wrestlemania 19.
The highpoint of the feud came when the Mania contract signing took place, with Vince laying out his feelings towards Hulkamania and how he never really needed Hogan in the first place. He then attacked the Hulkster and made him sign the contract in his own blood.
Even after their match was concluded, the two continued to feud with Hogan being forced to introduce the Mr. America gimmick after Vince forced him to take time off away from the screen.
It always seemed inevitable that these two would meet again after Hogan's first departure. Luckily they managed to fit it all in before it was too late for either of them.
