Taco Bell has already sold 100 million Doritos Locos Tacos

​What's orange, crunchy, filled with low-grade beef and extremely popular? The Doritos Locos Taco. Taco Bell's fusion of Dorito and taco is apparently more than a novelty -- it's now the most successful product launch in the chain's 50-year history, with 100 million sold during its first 10 weeks. To give you an idea of just how popular the DLT is, it took McDonald's 18 years to sell its first 100 million burgers. The launch has been so successful that the company saw a six-percent increase in same-store sales for the first quarter of this year. Expect to see more flavors soon, including a Cool Ranch flavored shell.​
