McDonaldland

McDonaldland was a fantasy world used in the marketing for McDonald's restaurants during the 1970s through the 1990s. McDonaldland is inhabited by Ronald McDonald and other characters such as the Hamburglar, Grimace, and Mayor McCheese. In addition to being used in advertising, the characters were used as the basis for themed equipment in the "PlayPlaces" attached to some McDonald's outlets, small recreational activity rooms intended for young children. The McDonaldland commercials featuring the full cast of characters were dropped from McDonald's advertising in 2003, but Ronald McDonald himself is still seen in commercials, Happy Meal toys, and other marketing.

The concept of McDonaldland was sufficiently similar to the 1969 television show H.R. Pufnstuf that the producers, Sid and Marty Krofft, successfully sued McDonald's for plagiarism.
