Beginning in the 1950s, Hanna-Barbera emerged as one of the greatest creators of Saturday-morning cartoons of the 20th century, thanks to properties like Scooby-Doo, The Flintstones and The Jetsons. As the company continued to produce excellent and popular shows, it built up a strong, nostalgic reputation that has endured well into the 21st century, despite the company being defunct. Along the way, the best characters and shows of the company have been given some fun comic books.
