I'm fascinated, when not irritated or infuriated, by the managed flow of Fat in media imagery. That is, the particular way that images of fat people are let in--or not--for public consumption. Everything is managed to varying degrees, but fat is its own particular problem--TV producers who don't like to feature fat people onscreen as witnesses, for instance, because they "lack credibility."
I can speak only to the print part of Martha Stewart's world (I haven't watched her TV show post-poncho) but there is almost NEVER fat in her magazine: no fat people in the little dinner parties, features on entrepreneurs, models, anything. There is actually a pretty specific beauty ideal attached to the MStew world (very scrubbed, subfusc, JCrew, spare/lean). So I was amused to see this in her blog the other day. Because sometimes you just have to let the fat in, baby. And then, I guess, you call it voluptuous. Which they certainly are, not even particularly fat, but--what can I say, I noticed it. Little essay on class-race-money-NYC-media-fame-etc. here.
