An interesting point that Meltzer always brigs up, is that Vince thinks he took wrestling mainstream, but in reality, wrestling is far less popular now than it ever has been in history.
WWE is highly successful, but wrestling as a whole does far less attendance, far less total TV viewers, far less viewers percentage wise when compared against the population, etc. By anything measurable, even gross income when changed for inflation, the wrestling industry has never been less popular than it is now.
Local wrestling used to do ratings that Vince has never approached, and they used to do it every week for decades on end in places like Memphis, Portland, Houston, St Louis, Atlanta, Carolinas, etc etc etc, not to mention selling out large arenas EVERY WEEK in some of those places, repeating the same tour loops week after week for decades. Vince cant sell out those same cities once per YEAR these days as the only game in town, even with his crazy budget and flashy looking TV production.
How did the territories keep things fresh week after week? Solid booking that made sense. Not by writing elaborate scripts, not by bringing in people from outside the business, not by running from the idea that what you do is wrestling. The booking was often done by uneducated men, but they were lifers in the business and understood what drew through trial & error and experience.
I think selling out the same buildings every week for years on end is far more impressive than drawing half full houses every night, and living and dying on PPV and the Mania revenue.
So from that angle, i'm not even sure Vince is a great wrestling promoter. He's a great something, I just don't know what it is.
