Yeah, I know, but the TMNT ratings still make it one of 4kids powerhouses at the moment, although I wonder what the Lost season will do to the ratings now. But don't forget 4kids gets royalties from all the TMNT merchandize, which makes them very happy. All the TMNT toys, T-shirts, bedsheets, backpacks, etc. they get some money on.
I remember on Murphy's blog he said a TMNT camo T-shirt deal with JCPenny would make Mirage and 4kids $30,000 in royalties, and that's just one T-shirt brand for one store!
I also suspect 4kids might want to keep TMNT alive until a possible movie sequal, and the earliest it could be released is 2010. Since 4kids bought out the WB saturday morning block for 5 years, its possible that this show could have another three or so seasons left in it.
