A little background first.
Recently Anita announced that she was looking for funding to examine sexism in videogames and the Internet exploded in the usual masochistic, misogynistic way, with countless anonymous trolls offering to find and rape/kill her, or asking her to "go make me a sandwich". Ha bloody ha.
Quote: Anita Sarkeesian is a media critic and the creator of Feminist Frequency, a video webseries that explores the representations of women in pop culture narratives. Her work focuses on deconstructing the stereotypes and tropes associated with women in popular culture as well as highlighting issues surrounding the targeted harassment of women in online and gaming spaces.
However, the other side of the internet rallied behind her, fully funding her kickstarter campaign and in the process rejuvenating many discussions about the treatment of women in the gaming industry.
Anyway, here's the first two episodes in her series. Don't be concerned if you're not up to speed on the latest in Videogames, she aims for a diverse audience and explains everything.
The Damsel in Distress Part 1
The Damsel in Distress Part 2
For completeness, here's her earlier series on Women vs Tropes in general media
