Maybe some folks have long term memory loss but alas, there was a time when the food network had much to offer for EVERYONE. In my opinion, as a pro, if you can learn from or take inspiration from a cook book, a class, or a youtube video, you can certainly learn from TV. I'm not elititist and never felt bound to PBS only (until now) because back in the day, FN had such awesome and educational programs as Chocolate with Jaques Torres, Bakers Dozen with Marion Cunningham, East Meets West with Ming Tsai, Rick Bayless, Mario Batali, Gale Gand (who will be a guest here on Cheftalk) and of course, Julia. When I was first starting out as a pro in the early 90's, I DID take inspiration from some of these shows and they were targeting an audience of foodies. While I agree that those days are long gone, I think it's a bit pretentious to assert that pro's are beyond learning from cooking shows. I don't know everything about Mexican cooking or Asian cooking - and according to St. Bourdain (who was ALSO on Food Network), one could live an entire lifetime and still continue to learn about these cuisines. Why on earth would it be more acceptable to learn from a cookbook or a class than a TV program?
Ideally, one would hope to learn on the job, under the tutelage of a great chef. But if you're cooking in a Mediteranean style restaurant, who is going to show you how to make great tamales? I suppose you could spend another ten years on the job, hoping for a chance to work in a great authentic Mexican restaurant where you might be taught these cuisines. Or, you could teach yourself.
Food TV has gone the way of MTV, IMO. Once, the latter network was devoted to music only and appealed to a predominantly rock audience (remember Michael Jackson couldn't get his video on there at first). Today, the only time you'll see a music video on MTV is 8am or 2am. The rest of the time is devoted to highlighting the general debauchery of tatooed and pierced bottom feeders and attention whores.
Rant over...for now...
