Pinky Official Website Who Owns The Right To Pinky And The Brain?

Who owns the right to Pinky and the Brain? - pinky official website

I see the Internet as Pinky and the Brain was by all major U.S. networks (Fox, Warner Brothers and Nickelodeon) and now I find Pinky and the Brain has been shown that Disney XD, which I find a list of time before shows are shown? Disney has always Pinky and the official website of the brain on the side? So who has the right, Pinky and the Brain?
