Sad fact: the huge success of Tiny Toons was what indirectly killed Hanna-Barbera studios. In the 90s, WBA had hit after hit and sold bucket loads of toys with their new cartoons, while HB made flop after flop, with Captain Planet being the biggest show they had at the time.
This lead to WB acquiring HB in the late 90s, and eventually shut down the studio as a whole, making Warner own all their IPs such as Flintstones, Yogi Bear and Scooby Doo.
