McDonald’s introduced Happy Meals in 1979. The fact that you know what they are proves they changed fast food forever.
This was a true industry-changer. Literally everyone knows what these were.
By the way, they still make them and do them. In case you wanted to see how much they’ve changed, just go buy one really quickly. Maybe you’ll like it too 😉
