This post is cross-posted with www.MissRepresentation.org, in advance of the film’s debut tonight on OWN, 9pm (8c).

In Miss Representation, actress-activist Rosario Dawson talks about how important it is for women to write their own stories. This is equally important in entertainment and in journalism alike.Yet as I discuss in the film, today’s media climate is extremely toxic for women and girls, and for people of color. That’s because the main purpose of TV programming today is not to entertain, engage or inform us. Sad but true: the purpose is generate sky-high profits for the six major conglomerates (Disney, Time Warner, NewsCorp, Viacom, CBS and General Electric) that own and control the vast majority of what we’re given to watch, see, hear and play in newspapers, magazines, TV, radio, movies, billboards and video games.

As a result, women are misrepresented and marginalized as op-ed writers, front-page news sources, lead anchors, and broadcast journalism commentators… that is, when they aren’t missing entirely (as decades of research document). Scripted entertainment isn’t much better. As filmmaker Nia Vardalos wrote at WIMN’s Voices, Hollywood studios ignore data that show that audiences actually do want to support films with strong female leads, calling the success of “Sex and the City” and “Mamma Mia” “a fluke.” When Nia tried to follow up her hit “My Big Fat Greek Wedding” with a new script, studio execs pressured her to change female leads to male characters—exactly the opposite of the kind of climate Rosario Dawson is rightly calling for.

DVR Alert: Tune in to the award-winning documentary “Miss Representation” TONIGHT, Oct. 20, 9pm(8c) on OWN (the Oprah Winfrey Network).

I had the honor of being an adviser on — and being interviewed in — this powerful film about women and the media. “Miss Representation” is the first mainstream film to delve into sexism in commercial media — from advertising and pop culture’s sexualization of girls, to triggering eating disorders, to media normalizing violence against women, to reality TV as anti-feminist backlash (which I discuss both in the film and Reality Bites Back), to double standards in news reporting on female politicians, to the trivialization of women who work in broadcast news, to the causal role advertising and media consolidation plays in all of this, to the need for media literacy to help youth and adults become more active, critical media consumers.

OWN will decide whether to re-air “Miss Representation” based in large part on the ratings it draws tonight. So please tune in… and ask five friends to set their DVRs as well. Tweet it, Facebook it, email people. (If for no other reason than the cognitive dissonance that results from seeing me and former Secretary of State Condoleezza Rice agree on something!)
