The business of pro-wrestling, especially during the territory era was incredibly fascinating...
From the alliances to the promoters to the bookers to the wrestlers.
There were probably 50+ wrestling shows a night across the US and Canada.
And the neat thing was that you could have a card in a gymnasium in Podung, Kansas that would draw 500 people while the same day 10,000+ would be watching a card at Greensboro, NC– And the card in Podung would have several "name" wrestlers that most would recognize.
It would be like the Yankees or Canadians or Lakers or Cowboys playing a game in your town.
