FedEx Corporation, originally Federal Express Corporation, is an American multinational conglomerate holding company focused on transportation, e-commerce and business services based in Memphis, Tennessee. The name "FedEx" is a syllabic abbreviation of the name of the company's original air division, Federal Express, which was used from 1973 until 2000. FedEx today is best known for its air delivery service, FedEx Express, which was one of the first major shipping companies to offer overnight delivery as a flagship service. Since then, FedEx also started FedEx Ground, FedEx Office, FedEx Supply Chain, FedEx Freight, and various other services across multiple subsidiaries, often meant to respond to its main competitor, UPS. FedEx assists in the transport of some United States Postal Service packages through their Air Cargo Network contract. FedEx's air shipping services are centered at its hub at Memphis International Airport. Wikipedia
