The Los Angeles city council has decided to preserve all three of the buildings that once comprised the historic Hanna-Barbera animation studio, where such TV icons as the Flintstones, Barney Rubble, Yogi Bear, Huckleberry Hound and Scooby-Doo came to life. “It was at the studio that Bill Hanna and his partner Joe Barbera perfected ‘limited animation,’ which is far cheaper than the traditional kind. It also involves far less movement of the animated characters, however, and thus is criticized by some purists. Hanna and Barbera perfected the cheap technique in the late 1950s, a time when the major studios were closing their labor-intensive animation departments, and thus some have credited them with helping save the cartooning industry.”
