09:35 "Enlightened Sexism" - why it's seen as OK to bring back sexist images of women.

Susan J Douglas, professor of Communications at the University of Michigan, columnist and author.

Susan J Douglas' latest book points out that women in general are still paid much less than men, and still battle that glass ceiling which still sees men in most of the top jobs.
