McDonaldland, McDonald’s fictional advertising world, debuted in 1971.
The campaign created a fantasy setting populated by characters such as Ronald McDonald, the Hamburglar, Grimace, and Mayor McCheese. These figures appeared in television commercials and other promotional material aimed especially at children.
McDonaldland helped turn McDonald’s branding into a recognizable shared universe rather than relying only on the restaurant name, food photography, and the Golden Arches. The campaign also linked individual characters to memorable visual designs and catchphrases.
People sometimes confuse McDonaldland’s debut with the introductions of individual characters. Ronald McDonald appeared before the broader fictional setting, while several other characters were added or revised after the world was established.
