Note: you have to get to the final third of this post before you get to the part about kinky sex, and while I have tried to write something that is safe for work, that might be debatable.
Colossal Pictures like all such entities would vary in size but perhaps at its largest might be about 100 people. ILM was perhaps a few hundred when working on Empire Strikes Back (1980) and was presumably about the same size or a little larger when working on Revenge/Return of the Jedi (1983). Pixar was certainly less than 100 people. A variety of other independents and experimental filmmakers who worked in the city perhaps added up to another few hundred. So a very rough estimate of those whose profession was the cinematic arts in any form in the greater Bay Area might be perhaps 700 or so people. Maybe even a few more if we include those teaching in the various schools, independent animators, people who lived in the Bay Area but worked mostly in LA, and so forth. I am deliberately leaving out the Game Industries and what we used to call Interactive Multimedia as that seems to be a different part of the entertainment industry, just as the music industry is a different part of the entertainment industry.
Although there are several corporate entities involved, the main production company, or perhaps the umbrella brand that then points to the individual sub-genres of kink is, logically, www.kink.com. Kink.Com has produced literally hundreds and hundreds of short films in a variety of genres of sexually oriented films usually with a kinky, S&M, B&D aesthetic. Although sex positive fantasy films are a bit controversial, some would say they are pornography, and not all Feminists and fellow travelers approve, they certainly seem to have a very positive attitude towards the whole genre. I noticed, not looking all too closely, that for example they would have an interview section after the main film where the actors and actresses would chat with each other about their experience and their feelings about each other after tying each other up and ... um, well, doing things to each other. It all seems very healthy to me if a bit specialized.
