Dr. Seuss Enterprises

Background
Dr. Seuss Enterprises is a global publishing and licensing company founded in 1993 to oversee Dr. Seuss' works. It was initially referred to on-screen as Cat in the Hat Productions, when Chuck Jones and MGM Animation/Visual Arts co-produced How the Grinch Stole Christmas! and Horton Hears a Who!, until DePatie-Freleng Enterprises took over animation production of the Dr. Seuss TV specials in 1971. Currently, Warner Bros. Entertainment through Turner Entertainment Co. owns How the Grinch Stole Christmas! and Horton Hears a Who!, while Warner also licenses the remaining material along with Dr. Seuss Enterprises.
