 Leading up to 2004, Pepsico conducted extensive research to develop a beverage with a taste and color to complement Taco Bell food products.The resulting product was named Mountain Dew "Baja Blast", a light blue-green colored, tropical-lime-flavored variety of the soft drink.Taco Bell was given a ten-year exclusive rights period during which Baja Blast would not be available in any store or other food outlet, not even to Taco Bell's fellow Yum!
