on character dialogue than detailed animation. The number of drawings for a seven-minute cartoon decreased from 14,000 to nearly 2,000, and the company implemented innovative techniques such as rapid background changes to improve viewing. Reviewers criticized the change from vivid, detailed animation to repetitive movements by two-dimensional characters. Barbera once said that their choice was to adapt to the television budgets or change careers. The new style did not limit the success of their animated shows, enabling Hanna–Barbera to stay in business, providing employment to many who would otherwise have been out of work. Limited animation became the standard for television animation, and continues to be used today in television programs such as The Simpsons and South Park. In 1966, Hanna-Barbera Productions was sold to Taft Broadcasting (renamed Great American Communications in 1987) for $12 million. Hanna and Barbera remained at the head of the company until 1991. At that point, the company was sold to the Turner Broadcasting System for an estimated , which itself merged with Time Warner, owners of Warner Bros., in 1996.

Hanna and Barbera continued to advise their former company and periodically worked on new Hanna-Barbera shows, including The Cartoon Cartoon Show series and hit silver screen versions of The Flintstones (1994) and Scooby-Doo (2002). Death Hanna died of esophageal cancer at his home in North Hollywood, Los Angeles, California on March 22, 2001, at the age of 90.

However, Barbera, unlike the other two, had an audio clip of his voice playing in his Cartoon Network promotional tribute. Hanna is buried at Ascension Cemetery in Lake Forest, California. Legacy Most of the cartoons Hanna and Barbera created revolved around close friendship or partnership; this theme is evident with Yogi Bear and Boo Boo, Fred Flintstone and Barney Rubble, Ruff and Reddy, The Jetsons family, and the friends in Scooby-Doo. These may have been a reflection of the close business friendship and partnership that Hanna and Barbera shared for almost 60 years. Professionally, they balanced each other's strengths and weaknesses very well, but
