Yogi Bear, created by Hanna-Barbera and voiced by Daws Butler, Greg Bursonis and currently by Jeff Bergman, is the lovable bear who made his debut in 1958 as a supporting character in 'The Huckleberry Hound Show'. By January of 1961 he had become more popular than Huckleberry Hound and was given his own show, 'The Yogi Bear Show'.

Yogi and his friends reside the fictional Jellystone Park, a variant of the real Yellowstone National Park. Yogi, accompanied by his constant companion Boo-Boo Bear, would often try to steal picnic baskets from campers in the park, much to the displeasure of Park Ranger Smith. "I'm smarter than the av-er-age bear!" and constant hunger is what usually led to his troublesome antics.

After becoming such a popular personality of cartoons and animated films, in 1983, a Yogi Bear balloon made its first appearance in the Macy's Thanksgiving Day Parade.
