Actually, not that new; it started years ago with the original Japanese show Iron Chef. I couldn't resist the comic campiness of Chairman Kaga's dramatics (like when he'd whip back the cloth to reveal the show's theme ingredient... "Kyo no tema wa..." fish innards!)
Now there are so many addicting food shows. Some of my personal favorites-
Food appreciation shows like Diners, Drive-ins and Dives (This is actually a family obsession. We will actually seek out the diners featured on this show when we are traveling - and have rarely been disappointed.)
The MG series I'm working on right now features a bit of the latter - the mom is a foodie on a travel show. I'm not really sure if I became more interested in these shows because of her character or if I created her character because of my interest in these shows...
How about you? Do you watch any food shows? What are your favorites?
