I think a lot of "cooking" shows are trending into foodie shows, cooking/travel shows, cooking reality shows... We might as well face the fact that there are more people interested in eating, in foodie travel, etc., than in actually cooking. Those who want to cook are in a minority and TV is all about getting the most number of people to watch.
I want to see chefs cooking definable recipes and demonstrating cooking methods. Even better if the show has a website and/or book so I can get written recipes for the ones I decide I want to cook for myself. I could care less about specific restaurants or foodie travel. I want to cook things myself in my own home. Anything that doesn't help me accomplish that is wasted time for me.
I almost always buy the cookbook for all my favorite cooking shows. I've gotten dozens of cookbooks that way, became enthused with the chef and the program, bought the book to get all the recipes instead of the very few I took notes on.
So to sum it up, I think TV cooking shows are trending away from chef provides recipe and demonstrates how to cook it, and trending towards reality, foodie, travel or a combination of them. That's not so good if all you want is directions on how to cook stuff yourself.
