The New Scooby-Doo Movies is the second incarnation of the Hanna-Barbera Saturday morning cartoon series Scooby-Doo, Where Are You!. It premiered on September 9, 1972 and ran for two seasons on CBS as the only hour-long Scooby-Doo series. Twenty-four episodes were ultimately produced (sixteen in 1972–73 and eight more in 1973–74). The New Scooby-Doo Movies was the last incarnation of Scooby-Doo to feature Nicole Jaffe as the regular voice of Velma Dinkley, due to her marriage and retirement from acting.
