Pizza Hut was founded in June 1958 by two Wichita State University students, brothers Dan and Frank Carney, as a single location in Wichita, Kansas. PepsiCo acquired Pizza Hut in 1977. Before closing in 2015, the oldest continuously operating Pizza Hut was in Manhattan, Kansas, in a shopping and tavern district known as Aggieville near Kansas State University. The first Pizza Hut restaurant east of the Mississippi River opened in Athens, Ohio in 1966 by Lawrence Berberick and Gary Meyers.

Pizza Hut is split into several different restaurant formats: the original family-style dine-in locations; storefront delivery and carry-out locations; and hybrid locations that have carry-out, delivery, and dine-in options. Some full-size Pizza Hut locations have a lunch buffet, with "all-you-can-eat" pizza, salad, bread sticks, and a pasta bar. Pizza Hut has other business concepts independent of the store type; Pizza Hut "Bistro" locations are "Red Roofs" which have an expanded menu and slightly more upscale options.
