Some of these cartoons were The Jetsons, The Flintstones, Scooby-Doo, Yogi Bear, Smurfs, Pink Panther, Wally Gator, and Peter Potamus, as well as the 1973 movie version of Charlotte's Web and many more. It was started by and named after William Hanna and Joseph Barbera. After the death of Hanna in 2001, Hanna-Barbera split into two parts: Warner Bros.
