The "G" in family movie ratings clearly doesn't stand for "girl-power." Researchers at the Annenberg School for Communications at the University of Southern California studied 101 kids' flicks and found that male roles predominate: three of four characters are male, and fewer than one in three of speaking roles overall belongs to a female. There's evidence that exposure to television is a "significant and positive" predictor of sex role acceptance and attitudes among children and adults. The study was study sponsored by the nonprofit Dads and Daughters and its See Jane program.
