McDonald's introduced the Happy Meal brand in 1979 as a children's meal promotion.
The original Happy Meal was designed as a boxed children's offering containing a hamburger or other main item, a side, a drink, and a toy. Its packaging and presentation turned a meal into a recognizable branded experience aimed at families.
The concept was developed before its national rollout through regional tests and promotional work. The first national United States Happy Meal promotion featured a circus-themed box, helping establish the collectible packaging and toy-centered identity associated with the brand.
The Happy Meal is sometimes confused with a particular toy campaign, but the name refers to the enduring meal brand itself. Toys, packaging themes, and menu choices have changed repeatedly, while the core combination of a children's meal and branded presentation has remained central.
