McDonald's is the largest distributor of toys in the world, and by far. 20% of all sales at McDonald's include a toy, with one being passed out with each Happy Meal the company sells.

A Happy Meal is a form of kids' meal sold at the fast food restaurant chain McDonald's since June 1979. A small toy is included with the food, both of which are usually contained in a red box with a yellow smiley face and the McDonald's logo. The packaging and toy are frequently part of a marketing tie-in to an existing television show, film, or toy brand.

In July 2011, McDonald's announced plans to make Happy Meals healthier, including the addition of apples. The redesigned meals will contain a smaller portion (1.1 ounces) of fries, along with the apples. On February 4, 2013, McDonald's announced that Fish McBites, fried Alaskan pollock, the same fish used in Filet-O-Fish, would be added as an entree, which would run until March, intended to coincide with Lent.

On November 1, 2013, McDonald's started giving out books with its Happy Meals instead of toys. This was just one in a long string of attempts by McDonald's to change the image of its Happy Meal, which has come under fire for playing a role in childhood obesity. The books ended for children on November 14, when McDonald's switched back to giving out toys.
