The Happy Meal became McDonald's first major children's meal when it launched nationally in 1979.
The meal combined a child-sized serving of food with a toy and distinctive packaging. Its design made the meal itself part of McDonald's branding rather than simply a smaller adult order. The box, colorful graphics, and collectible toys gave children a reason to recognize and request the product.
The Happy Meal was tested in selected markets before its national United States launch. The concept had been developed in the late 1970s, with advertising executive Bob Bernstein associated with its creation. McDonald's later used licensed entertainment properties and recurring toy promotions to reinforce the product's identity.
The Happy Meal is sometimes confused with McDonaldland, the fictional advertising world that also targeted children. McDonaldland was a campaign setting with characters, whereas the Happy Meal was a menu product and packaging platform. Its branding influence extended well beyond the food inside the box.
