Did the company have any direct involvement, or ownership of some flavor, in hotels, hotel entertainment systems/services, cable systems or content providers, or publishing activities (print or video)?
My impression is that it’s less pronounced now, since the internet has eaten at the margins and made wide-scale distribution by relatively tiny entities much easier; but in the not-so-distant past, all kinds of Respectable Corporate Entities either had subsidiaries in the media distribution business, or had direct operations which (usually discretely) pulled in some nontrivial income from porn. (Most notable instance I can think of recently is the whole flap with Romney, Mr. Squeaky-clean-family-values trying to distance himself from Marriot, whose in-room entertainment systems stocked (and made good money on) porn of various flavors.) I think that they’ve since stopped, mostly because selling $12 porn films to somebody who has a laptop and internet access is fairly futile; but they did until recently.
A lot of the actual production was always done at arm’s length, since that could be done by small-scale outfits and the sleaze factor was high; but content distribution, porn not excepted, is a part of the corporate family in quite a few places.
