Which McDonald's character was introduced in 1963 as a clown to promote the restaurant?

Ronald McDonald was introduced in 1963 as a clown to promote McDonald's restaurants.

The character was created for television advertising and quickly became the company's most recognizable mascot. His bright clothing, red hair, and clown persona were designed to appeal particularly to children and families. Ronald's image helped McDonald's build a distinctive emotional identity beyond its food and logo.

Ronald McDonald later became the central figure in McDonaldland, a fictional setting populated by additional characters. The Hamburglar, Grimace, and Mayor McCheese helped turn advertising into a recurring branded world, while Ronald served as its best-known host.

Ronald did not replace the Golden Arches; the character worked alongside the logo and restaurant design. He also came after Speedee, the earlier mascot associated with the company's original emphasis on fast service.
