It’s been more than a year since we first told you about Taco Bell testing out the wild, finger-staining notion of selling its tacos in hard shells made out of Doritos. The product finally launched nationwide in March and is already the most popular new item the fast food company has ever launched.

The OC Register reports that 100 million Doritos Locos Tacos were sold during the first 10 weeks following the national launch, booting the Crunchwrap Supreme from the spot it had held since 2005.

From the Register:

To put some perspective on the 100 million tacos sold, Taco Bell notes that McDonald’s sold its first 100 million burgers in 1958 – 18 years after the first McDonald’s burger stand opened, and three years after Ray Kroc started his first McDonald’s franchise.
