Google Pimps for Cartoon Network?

Unless I’m mistaken, this is the first time Google has used a modern commercial entity as part of their search engine ‘doodle’. I remember when they did a doodle for Popeye, but that was a 115th birthday celebration of the original cartoonist who created Popeye. Scooby-Doo, the original TV cartoon is currently owned by Cartoon Network, which presumeably would have to have given permission for its use.
