Ronald McDonald was introduced in 1963 as McDonald's principal branded mascot and a personification of its hamburger identity.
The character began in local advertising and was designed as a colorful, friendly clown who could appeal especially to children. McDonald's gradually expanded Ronald's role through television commercials, restaurant appearances, toys, and the fictional McDonaldland setting.
Ronald is sometimes confused with Speedee, the earlier chef-like symbol used by McDonald's during its first decades. Speedee represented fast service, while Ronald became the better-known face of the company’s family-oriented branding.
Although Ronald's costume and supporting characters changed over the years, the core design remained recognizable: red hair, clown makeup, yellow clothing, and a strong association with McDonald's restaurants.
