Starbucks (NASDAQ: SBUX) CEO Howard Schultz has already changed the American coffee-drinking experience. His company has made its variant of the European cafe ubiquitous, with over 13,000 locations in the United States and 25,000 across the globe. Starbucks’ influence has gone beyond its own stores as its success led to rivals including McDonald’s and Dunkin’ Brands’ Dunkin Donuts adding espresso-based drinks.
