30 Vintage Photos of Fast Food Restaurants Over the Years
McDonald’s
McDonald's launched its first outlet way back in 1940. Hamburgers were one of their fastest-selling items. The fast-food chain started gaining popularity in the early 1960s, although it didn't launch its first TV commercial until 1963.

McDonald's was once a hot-dog stand, and it has come quite far in all these years. At one point, the fast-food chain was the largest distributor of toys in the world, all thanks to its kid-focused Happy Meals.
KFC
Founded by a person named Harland Sanders - aka Colonel Sanders - KFC (Kentucky Fried Chicken) has become one of the most popular fast-food chains across the globe.

KFC first began serving fried chicken at a petrol station that Sanders owned, which he later converted to a fast-food outlet. KFC's first official outlet was opened in Salt Lake City in 1952. The KFC recipe is still a top secret and so, it's locked up safely in the vault of its headquarters.
