Ruby-Spears Enterprises

Ruby-Spears Enterprises was an animation studio founded in 1977 by Joe Ruby and Ken Spears, who were former writers for Hanna-Barbera.

Like Hanna-Barbera, Ruby-Spears was eventually merged into Warner Bros. Animation, who currently owns every production Ruby-Spears did with the exceptions being Rambo: The Force of Freedom, which is owned by StudioCanal and It's Punky Brewster, which is owned by NBCUniversal.
