The first choice: do you want your sandwich to be '6-inch' or 'footlong'. Then there are 5 types of bread, 11 toppings, and 9 dressings and sauces to choose from - making for an almost endless combination of possibilities. These choices involve consumers in the brand, allowing them to 'make it their own' and giving them a reason to keep coming back.

And in a deliberate strategy targeting rivals such as McDonald's and Burger King, SUBWAY have positioned themselves as the healthy choice: offering sandwiches with '6 grams of fat or less' as well as salads and other low-fat options.

SUBWAY was established in the USA in 1965 by 17-year old founder, Fred DeLuca. Now, there are nearly 24,000 SUBWAY stores in over 80 countries, and the company estimates that about 1,900 SUBWAY sandwiches are served every minute around the world. It's the biggest fast-food chain in the USA, and the company aims to overtake McDonald's globally by 2009.
