1. Dr. Pepper
The impact of this drink has grown by leaps and bounds since it started in a little town in Texas. Dr. Pepper can now be found in most vending machines in Japan. I always describe it as a mix of root beer and Coca Cola.
This tasty combination of cookie and caramel may not have been invented in Texas, but the world owes the Mars Chocolate North America factory in Waco for its continued production. Roughly 50-75% of Snickers in the world come from Texas.
