Little Bill

Little Bill is a cartoon character sprouted from the fertile mind of Bill Cosby. The show is based on Cosby's popular book series and is developed through research and in consultation with a panel of educational consultants. The show is designed to help kids celebrate their everyday experiences and the people who share them. Little Bill shows kids that what they do makes a difference in the world. By dealing with conflicts encountered in everyday life, the program encourages children to value the love of their family, to increase self-esteem, and to develop social skills.

Little Bill's signature is saying, "Hello Friend!" This saying was inspired by the Hello Friend/Ennis William Cosby Foundation, established in memory of the goals and dreams of Ennis William Cosby, the son of the show's creator.
