Enchanted Voyage took riders on a boat ride into a huge television set, where they would encounter figures from the Hanna-Barbera cartoons.
KECO, the company which owned Kings Island in it's original incarnation and also the owner/operator of Coney Island Cincinnati, was a significant media company in the 1970s owning many television affiliates across the US. Hanna-Barbera was a property which they had some degree of stake in and as such this was utilized as an early example of IP based attractions in a post-war US theme park.
