Playgirl started making films in 2005. So yes, this study does not seem to be comprehensive in its sources.
I have a funny story about a Suze shoot; she shot my friend Derek for Playgirl, and he really enjoyed working with her.

I don't film content, but have written stories and scripts for Sssh and scripts for Blush Erotica, erotic stories and DVD cover copy for Playgirl, erotica
director Angie Rowntree, and Lilly Sparks' Afterglow to the list of excellent feminist porn sites--in addition, check out older titles from the likes of Playgirl
