Most of us go through life thinking that the McDonald’s logo is supposed to be the letter “M” for McDonald’s. But the original golden arches were actually a part of the building design for the restaurant chain. The arches connected to an overhang that kept the rain off of customers when they were ordering outside. The company discovered that those golden arches were easily seen from the freeway, which drove people to the restaurant. This is partially why the golden arches are still used as a symbol of the brand today.
