I only recall two cooking shows from my childhood, one was a British dude called "The Galloping Gourmet" and the other, of course, was Julia Child.
Today, decades and hundreds of channels into the evolution of the medium, there are more cooking shows than there were shows back in the day.
I personally have learned quite a bit by watching many of these cooks and dare I say, I've been entertained. I've even thought in some odd way how much I'd like to go to culinary school at some time, if only for the experience.
Of late, cooking shows have merged into the reality TV genre and after watching a number of them, I sometimes fantasize about participation.
