As its name implies, the company's main focus was originally donuts. However, today it has emerged as a major player in the coffee market, making it a direct competitor of Starbucks. Located in more than 32 countries, Dunkin' Donuts has over 10,000 locations, with 70% of those located in the US. The vast majority of the US Dunkin' Donuts franchises are located east of the Mississippi. While many Dunkin' Donuts stores are freestanding, there are also locations in gas stations, food courts, supermarkets and some Wal-Mart stores, particularly in the northeastern part of the US.
