How would WWE be different if, TNA, and WCW, never existed?

Well that would of left just WWF/WWE, alone in competition with ECW, but ECW and WWF/WWE had made some agreements and they teamed with WWF/WWE for a little while. ECW would of eventually fell because it was as its name Extreme Wrestling and injuries start to pile up and then would eventually fail. WWE would be a lot different we would of maybe not have had the Attitude Era because that was in competition with WCW, we might of still been stuck with the original WWF which was good in my eyes
