Las Vegas was where most boxing matches were held. It could even be called the "Holy Land of Boxing" in the US, and because Las Vegas was also the "Gambling Capital" of the world, it had the most developed betting industry in the world.
Before the nineties, American boxers gathered in New York because New York was the most developed and heavily populated city in the US. In New York, any sport would be able to find a vast market, and many world boxing championships were held in the Madison Square Garden back then.
However, because a gambling ban was written into the legal provisions of New York, the development of the boxing industry was greatly restrained. Since then, Las Vegas began its "marriage" with boxing. With the support of casinos, bookmakers, and betting businesses and groups, the boxing industry developed rapidly in Las Vegas, ultimately achieving its current status.
