On the production side, very few, if any. One thing about the "mainstreaming" of porn is that the mob has moved onto other things, and less-stringent rules and new production technology means there isn't an "underworld incentive" to get involved or it costs tens of thousands of dollars just to run a camera to film. The decline in porn magazines as well figures; finding a printer who's willing to do porn is still tough, but its not like ten or twenty years ago where the only printers doing it were mob-connected.

When it comes to strip clubs, local escort agencies and brick-and-mortar porn stores? There's still a considerable presence. Not nearly as large as what I imagine it once was, but there's still money laundering, local official bribing, drug running and tax evasion. Its mainly concentrated in Las Vegas, Chicago, Florida and surprisingly Atlanta which has come up more and more.

There's been claims that the mobs been responsible for some of the larger porn bootlegging schemes but I don't think that's the case; maybe overseas, but not stateside.

Its just so much more profitable to deal with drugs where they have a monopoly on production and distribution.
