Subway (also known as Doctor's Associates Inc. ) 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" 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. It has since expanded to become a global franchise.
Subway is known for its wide array of topping choices allowing the customer to choose which toppings they want on their sandwich. Subway was also known for their slogan "Eat Fresh" implying the companies dedication to fresh ingredients on their sandwiches.
It is one of the fastest-growing franchises in the world and, as of October 2019, had 41,512 locations in more than 100 countries. More than half its locations are in the United States. It also is the largest single-brand restaurant chain, and the largest restaurant operator, in the world. Its international headquarters are in Milford, Connecticut.
Subway opened its first restaurant in India in 2001 in New Delhi. In deference to Hindu beliefs, Subway restaurants in India do not serve beef products; on the other hand, the country's large number of vegetarians has induced Subway's Indian outlets to offer a much extended range of vegetarian options. As of January 2017 there were 591 Subway restaurants in 68 Indian cities.
