Hanna and Barbera traveled in completely different social circles. Hanna's personal friends primarily included other animators; Barbera tended to socialize with Hollywood celebrities. Their division of work roles complemented each other but they rarely talked outside of work since Hanna was interested in the outdoors and Barbera liked beaches, good food and drink. Nevertheless, in their long partnership, in which they worked with over 2,000 animated characters, Hanna and Barbera rarely exchanged a cross word. Barbera said: "We understood each other perfectly, and each of us had deep respect for the other's work." Hanna is considered one of the all-time great animators and on a par with Tex Avery. Hanna and Barbera were among the most successful animators on the cinema screen and successfully adapted to the change television brought to the industry. Leonard Maltin says the Hanna–Barbera team "[may] hold a record for producing consistently superior cartoons using the same characters year after year—without a break or change in routine. Their characters are not only animated superstars, but also a very beloved part of American pop culture". They are often considered as Walt Disney's only rivals as cartoonists. Hanna and Barbera had a lasting impact on television animation. Cartoons they created often make greatest lists. Many of their characters have appeared in film, books, toys, and other media. During the 1960s their TV shows had a worldwide audience of over 300 million people and have since been translated into more than 20 languages. The works of Hanna and Barbera also have been recognized for their music, such as The Cat Concerto (1946) and Johann Mouse (1952), called "masterpieces of animation" in part due to their use of classical music. In all, the Hanna–Barbera team won seven Academy Awards and eight Emmy Awards, including the 1960 award for The Huckleberry Hound Show, which was the first Emmy awarded to an animated series. They also won these awards: Golden Globe for Television Achievement (1960), Golden IKE Award—Pacific Pioneers in Broadcasting (1983), Pioneer Award—Broadcast Music Incorporated (1987), Iris Award—NATPE Men of the Year (1988), Licensing Industry Merchandisers' Association Award for Lifetime Achievement (1988), Governors Award of the Academy of Television Arts and Sciences (1988), Jackie Coogan Award for Outstanding Contribution to Youth through Entertainment Youth in Film (1988), Frederic W. Ziv Award for Outstanding Achievement in Telecommunications—Broadcasting Division College—Conservatory of Music University of Cincinnati (1989), stars on the Hollywood Walk of Fame
