Why was the original Scooby Doo Cancelled?
When Scooby-Doo, Where are You! first aired in 1969 under Hanna-Barbera, it aired on CBS and only ran for, you guessed it, two seasons, ending in 1970. Ratings were declining and Hanna-Barbera scrapped it, taking a two-year hiatus for production before releasing a new series called The New Scooby-Doo Movies in 1972.
