So in Everyday with Rachel Ray's Decemeber issue they have a feature called Smell-O-Vision.
Wow I was Amazed!! The food smells so good and authetic. It would be nice if this sort of thing caught on. Like get a booklet in the mail or at the store to go along with what your watching. Inside the booklet different smells for different parts of the show. Would be awesome for Food shows like this or ones where you wonder how it smells.
