CNS has never made a Scooby-Doo series. WB has only ever produced it. The only Scooby project that CNS (or was it H-B before it became CNS) did was Night of the Living Doo back in '01 I think. Either way, both What's New Scooby Doo and Shaggy and Scooby Doo Get A Clue are both produced at WB, who sadly own the rights right now. And I don't think they'll produce another Scooby series, seeing as how Joe Barbera and Iwao Takamoto, the last people involved with Scooby, died a couple years back. It's a possibility though, since WB is in a huge slump right now when it comes to producing shows, so Scooby could actually save them. If not, I think WB needs to hand over the rights to Cartoon Network. Ted Turner should've never sold H-B.
