When Wayne DeMilia had his 'differences' with the IFBB, and eventually went their separate names, Wayne had the rights in the US to the name Night of Champions, and I think also Pro Division. Which is why the IFBB did not use that name, and Steve Weinberger used the New York Pro.
In 2005, that was the first year for the New York Pro. It was held at the Tribeca, holds about 900-1000 seats or so. The City Center, where Wayne held the last one, held about 2,500 seats. Yes - there was a difference in how many people can go to the show.
The situation last year in interesting, as that was the first New York Pro. Let's see what surprises will be in store for this years New York Pro, besides King Kamali and many others going to compete in it.
