Subjects covered in Ripley's cartoons and text ranged from sports feats to little known facts about unusual and exotic sites; but what ensured the concept's popularity may have been that Ripley also included items submitted by readers, who supplied photographs of a wide variety of small town American trivia, ranging from unusually shaped vegetables to oddly marked domestic animals, all documented by photographs and then depicted by Ripley's drawings.
Ripley's cartoon series was estimated to have 80 million readers worldwide, and it was said that he received more mail than the President of the United States.
He became a wealthy man, with homes in New York and Florida, but he always retained close ties to his home town of Santa Rosa, California.
Ripley's ideas and legacy live on in Ripley Entertainment, a company bearing his name and owned since 1985 by the Jim Pattison Group, Canada's 3rd-largest privately held company. Ripley Entertainment airs national television shows, features publications of oddities, and has holdings in a variety of public attractions, including Ripley's Aquarium, Ripley's Believe it or Not! Museums, Ripley's Haunted Adventure, Ripley's Mini-Golf and Arcade, Ripley's Moving Theater, Ripley's Sightseeing Trains, Great Wolf Lodge overlooking Niagara Falls, Guinness World Records Attractions, and Louis Tussaud's wax Museums.
