What was the name of McDonald's 1970s fantasy advertising setting?

McDonald's 1970s fantasy advertising setting was called McDonaldland.

McDonaldland was a fictional world created for McDonald's marketing, populated by characters such as Ronald McDonald, Mayor McCheese, Grimace, the Hamburglar, and Captain Crook. The setting gave the company a connected story world rather than a collection of unrelated product advertisements.

The campaign was aimed primarily at children and used colorful costumes, television commercials, restaurant promotions, and licensed merchandise. Characters represented hamburgers, milkshakes, fries, or playful roles, allowing ordinary menu items to become part of an imaginary landscape.

McDonaldland is sometimes confused with the name of the restaurant chain itself. McDonald's is the corporate and restaurant brand; McDonaldland was the fictional advertising environment. The setting also became associated with legal disputes over character designs, including litigation involving the creators of H.R. Pufnstuf.
