What is somewhat ironic is that what happened with the mob in Vegas when big corporations started buying an building casino's in the late 1980s and early 1990s actually first happened in the mid 1960s, when Howard Hughes practically bought up every mob invested casino.
Luckily for the mob, Hughes went crazy and sold all his casino's as quickly as he had bought them, so the mob could make a comeback in the early 1970s. That's when the movie Casino begins.
Yeah, the 1960's is when the New York families and others around the country outside of the mid west sold off most of their interests. But the families in Chicago, Detroit, Cleveland, Milwaukee, Kansas City, and St. Louis continued to have interests in the 1970's and into the 1980's.
To answer the original question, there is really no direct mob involvement in the casinos in Vegas now. That was gone by the mid-1980's. There doesn't seem to be even indirect involvement, like mobbed up companies getting ancillary contracts with the casinos like was the case when Atlantic City legalized its casinos. Even a decade ago what was left of mob involvement in Vegas centered around street rackets like loansharking, the escort business, telemarketing scams, etc. As well as some remaining ownership in some bars, restaurants, and strip clubs.
