MacFarlane was recruited during the senior film festival by development executive Ellen Cockrill and President Fred Seibert. He went to work at Hanna-Barbera (then Hanna-Barbera Cartoons) based on the writing content of The Life of Larry, rather than on cartooning ability. He was one of only a few people hired by the company solely based on writing talent. He worked as an animator and writer for Cartoon Network's Cartoon Cartoons series. In 1996, MacFarlane created a sequel to The Life of Larry entitled Larry & Steve, which features a middle-aged character named Larry and an intellectual dog, Steve. The short was broadcast as one of Cartoon Network's World Premiere Toons. He described the atmosphere at Hanna-Barbera as resembling an "old-fashioned Hollywood structure, where you move from one show to another or you jump from a writing job on one show to a storyboard job on another". MacFarlane worked on four television series during his tenure at the studio: Dexter's Laboratory, Cow and Chicken, I Am Weasel, and Johnny Bravo. Working as both a writer and storyboard artist, MacFarlane spent the most time on Johnny Bravo. He found it easier to develop his own style at Johnny Bravo through the show's process of scriptwriting, which Dexter's Laboratory, Cow and Chicken, and I Am Weasel did not use. As a part of the Johnny Bravo crew, MacFarlane met actors and voiceover artists such as Adam West and Jack Sheldon of Schoolhouse Rock! fame. Meeting these individuals later became significant to the production and success of his Family Guy series.
