Cartoon Network's odd treatment of Be Cool Scooby-Doo has broken several records for the franchise as a whole, including:
The current hiatus in the US is the longest mid-show hiatus in the history of the Scooby-Doo franchise. The record was broken on March 17, 2017, breaking Scooby-Doo! Mystery Incorporated's previous record of 1 year and 4 days ("All Fear the Freak" aired on July 26, 2011, while the next episode, "Night the Clown Cried" did not officially air in the US until July 30, 2012).
This is the first show to switch networks/platforms in mid-airing.
This is the first series not to air on TV (in the US).
