Here's the history: Fred De Luca borrowed $1,000 from family friend Dr. Peter Buck to start his first sandwich shop in 1965, when he was only 20 years old. He was trying to raise money to pay for college. He chose a mediocre location for his shop, but by noon on the first day of the opening, customers were pouring in. On the radio advertisement they had promoted the name as "Pete's Submarines", which sounded like Pizza Marines, so they changed the name to "Pete's Subway"; eventually it was shortened to "Subway", as it is known to this day. As of January 2008, the company has over 28,700 franchised locations in 86 countries and produces US$ 9.05 billion sales every year. In 2007, Forbes magazine named DeLuca number 242 of the 400 richest Americans with a net worth of 1.5 billion dollars. When the company was founded, Dr. Peter Buck, co-founder, was a scientist with a doctoral degree, and Fred DeLuca had aspirations of becoming a medical doctor. Hence the name Doctor’s Associates, Inc. In addition to traditional restaurants, Subway operates in many non-traditional locations. For instance, there are over 900 Subway locations inside of Wal-Mart stores and 200 on military bases, including several in Iraq, in addition to three located inside The Pentagon - as well as an increasing number on college and university campuses. There is at least one adults-only Subway, located at Foxwoods Resort & Casino. It is accessible only after entering a gaming area which is restricted to guests 21 and over, but it also has a drive thru. Subway restaurants has been consistently ranked in Entrepreneur Magazine's Top 500 Franchises, and was selected as the #1 overall franchise in 2008. Additionally, it was ranked as the #1 "Fastest Growing Franchise", and the #1 "Global Franchise" as well.
