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 was opened in Athens, Ohio, in 1966 by Lawrence Berberick and Gary Meyers. The company announced a rebrand that began on November 19, 2014, in an effort to increase sales, which had dropped in the previous two years. The menu was expanded to introduce various items such as crust flavors and 11 new specialty pizzas. Work uniforms for employees were also refreshed.
