There is an episiode of Dollhouse which briefly touches on the same issues (in fact, the whole series is an essay on female/male relationships, 'paying for it', concepts of slavery, feminism and so on - very dark undertones). I also think there has been an episode of CSI that has some elements (I only saw the clip on YouTube not the whole episode). It is slowly creeping into the mainstream media.

Unfortunately, I think the ProDomme industry is the one most vanillas are aware of. They seem to assume that a man has to pay a Mistress to get her to do what he wants her to do which brings in issues of Topping from the bottom as well. Its a huge misconception but one that is supported by the media. Every single TV mention of Femdom involves a Professional dungeon (including a documentary on the topic) and everytime a Mistress gets unfortunately splashed all over the tabloids it is because either she has been caught 'running a house of ill repute' or, more likely, has been servicing celebrities and been caught. I can't think of any film, TV show or r/l media event where a Mistress is portrayed as part of a loving, long term, lifestyle couple. Which is a shame.
