My take on the subject is that wrestling was the "cool thing" to get into, thus attracting a lot of real casual fans who might have had a passing interest in it. Hulk Hogan being a heel, the NWO's dominance, and the emergence of the Stone Cold character all contributed to this. I remember back in high school (My freshman year started in '96, and I graduated in 2000 so it basically covered the bulk of the Monday Night War) - we had a core of die-hard fans, myself included, and then there was a large number of casual fans. After a Nitro or Raw or even Thunder came to town, you'd see a bunch of people in the school wearing NWO or Austin shirts because it was the "in thing" at the time. Like all fads, it played out, and the extremely casual fans found something else.
