Adults who were children in the 1960s and 1970s have fond collective memories of whiling away Saturday mornings parked in front of the family television set watching cartoons. For many, pajamas were the clothing of choice, and breakfast was often multiple bowls of cereal and milk or donuts, eaten solo or with siblings as parents slept in late. And for many, a favorite cartoon featured the animated Great Dane, Scooby-Doo.
