Subway (also known as Doctor's Associates Inc.[4]) is an American fast food restaurant franchise that primarily sells submarine sandwiches (subs), salads and beverages. It was founded by the 17 year old Fred DeLuca and financed by Peter Buck in 1965 as "Pete's Super Submarines"[5] in Bridgeport, Connecticut. The restaurant renamed to Subway two years later, and a franchise operation began in 1974 with a second restaurant in Wallingford, Connecticut.[6] It has since expanded to become a global franchise.
