When Cosby was about 35 years old in 1972, he received an MA from UMass Amherst and was also back in prime time with a variety series, "The New Bill Cosby Show". However, this show lasted only a season. More successful was a Saturday-morning cartoon, "Fat Albert and the Cosby Kids", hosted by Cosby and based on his own childhood. That series ran from 1972 to 1979, then ran as "The New Fat Albert Show" in 1979, and finally ran as "The Adventures of Fat Albert and the Cosby Kids". In 1984, Cosby wrote a dissertation: "An Integration of the Visual Media Via 'Fat Albert And The Cosby Kids' into the Elementary School Curriculum as a Teaching Aid and Vehicle to Achieve Increased Learning". This was as partial fulfillment for his 1976 doctorate in education from UMass. Subsequently, Temple University granted him his bachelor's degree on the basis of "life experience".
