Regarding the Food Network

I happen to be an avid  Food Network viewer, and I have recently noticed what cannot properly be construed as a problem, but more of an observation on the nature of the programming.
As I was watching this past week's "Restaurant: Impossible" episode today (thank God for the wonder that is TiVo), I noticed a promo for the upcoming season of "Extreme Chef", a show which, in its first season, failed to excite anyone and only lasted a few episodes if I remember correctly. The basic premise was a "Chopped"- type competition, where four chefs compete in three rounds, with one getting eliminated after each one, leaving one lucky winner with $10,000. The nature of these challenges was "extreme", as they termed it, meaning that contestants had to swim across a lake to get ingredients, cook in a tornado, or plunge their hands into the chests of screaming Indians such that they could delicately prepare his still-beating heart for the judges, often including Simon Majumdar (who would criticize just about everything involved in the process).
As far as we could tell, the only other rules were that the token woman/homosexual always got eliminated first, and that the final round was always between the classy restaurant chef and the Conan the Barbarian impersonator who fricasseed dead racoons in backwoods Kansas for a living, but knew how to "cook real good". It was a toss-up.
At any rate, this upcoming season appears to only feature seven chefs, but in a more global setting, meaning that the chefs will travel around the world throughout the competition. This actually appears to be a more interesting premise for the show, but my first thought was "wait...this is just a spoof of "The Amazing Race".
Of course, once I realized this, I started thinking about all the other Food Netwrok Shows, and came to an important conclusion: Other than instructional shows ("30 Minute Meals", "Aarti Parti", etc.), shows that tour different culinary locations ("Diners, Drive-ins, and Dives", "Heat Seekers", "Kid in a Candy Store"), educational shows ("Good Eats", "Unwrapped") and "Throwdown With Bobby Flay". NO SHOW ON THE NETWORK IS ACTUALLY ORIGINAL.
Think about it. Even "Iron Chef America", their signature show, comes directly from "Iron Chef". "Chopped", the newest big thing, is essentially an expansion of the secret ingredient aspect of "Iron Chef", though admittedly with some additional creativity regarding the elimination process.
I have assembled a semi-complete list, detailing the Food Network show, and the show it is based off of on TV. It will not be complete, as I cannot remember every show to air on the network off the top of my head.

Again, not complete, and I'm likely missing some significant shows, but I think the connection is clear. It is only honest to point out that I still watch and will continue to watch many of the shows on the chart, as I personally find them entertaining, but it remains a curious observation (note to whoever thinks up these shows-try something original, please). Just some food for thought on a fast day, I suppose.
