What WWF PPVs were blacked out in the city they took place? I know for sure that WM3 was, I'm fairly sure WM6 was too. Was WM8 blacked out in Indianapolis? Given they were running a huge stadium at a time the business was down, I suspect it would have been.
SummerSlam '92 was effectively blacked out in the UK, not being shown on Sky Sports until a couple of days later (it aired 1 day later in the US).
I don't know about Royal Rumble '97, I know they had to paper the hell out of the Alamodome to draw a respectable crowd.
