The Happy Meal is a kids' meal sold at McDonald's since June 1979, typically containing a main item (like a burger or Chicken McNuggets), a side (fries or apple slices), a drink, and a small toy or book, all packaged in a distinctive red cardboard box with a yellow smiley face. The concept originated with Yolanda Fernández de Cofiño in Guatemala in the mid-1970s, who created a "Menú Ronald," but it was Bob Bernstein who developed and named the "Happy Meal" in 1977, leading to a national rollout in 1979. The meal's contents vary by country, often including healthier options like apple slices or salads, and it frequently serves as a marketing tie-in for films and TV shows, starting with the Star Trek Meal in December 1979. Over the years, McDonald's has faced safety and suitability issues, recalling Playmobil toys in 1982 and withdrawing Batman Returns toys in 1992 due to parental complaints. In July 2011, McDonald's announced plans to make Happy Meals healthier, reflecting ongoing efforts to address nutritional concerns. Today, the Happy Meal remains an iconic and enduring part of McDonald's brand, evolving with consumer preferences while maintaining its core appeal to children.
