Back in March, Taco Bell released its Doritos Locos Tacos nationwide.  If you somehow missed it, those are Taco Bell tacos with a hard shell made out of Doritos.

--And now, Taco Bell says that it's their most successful product ever . . . and it just might be the MOST SUCCESSFUL FAST FOOD ITEM OF ALL TIME.

--In the first 10 weeks, Taco Bell has sold more than 100 million Doritos Locos Tacos.  In comparison, it took McDonald's 18 years to sell its first 100 million hamburgers. 

--Full sales data isn't available on an item-by-item and restaurant-by-restaurant basis, so it's hard to tell if another chain sold that many units of any item quicker.

--Taco Bell's previous sales record was the Crunchwrap Supreme.  They didn't give the exact numbers, but they did say it was so popular when it debuted in 2005 that they made it a permanent menu item in 2006.

--Now that the Doritos Locos Tacos are so successful, Taco Bell is planning to expand and try OTHER Doritos-flavored shells.  The current ones are nacho cheese . . . Cool Ranch Doritos Locos Tacos will most likely be next in line.
