In the pre-Hogan era, the (W)WWF was a more rough and tumble environment, in which fairly intense brawling was the norm. The Madison Square Garden audience was mostly comprised of working class ethnic communities - hence the popularity of Italian-American Bruno Sammartino and Puerto Rican Pedro Morales - who paid to see their proxy heroes fight, not entertain. Their struggles were epitomised and vanquished by their champions.
The emergence of Hulk Hogan evolved - or devolved - that ethos. The WWF targeted the family audience during their national expansion programme in the early nineties, adopting the same production technicolour of its newest top star, Hulk Hogan.
As the WWF broadened its audience, it broadened its in-ring style, implementing the most basic mode of its trademark "storytelling" approach. Hogan, gigantic of height and engorged with muscle, was somehow the underdog in his matches - whether it was Andre The Giant or the smaller Randy Savage in the opposite corner.
Feeding off their rapturous support, he would deploy his famous "hulking up" routine just as it was felt all hope was lost, no-selling the protracted offence of his dastardly foes to underscore the virtue of saying your prayers and taking your vitamins.
