Forget the Echo. The Dot Is the Most Important Alexa Device

They've bought millions of Alexa-powered devices. When you think about Alexa, you're probably thinking about the Echo, the tall, cylindrical monolith that first introduced Amazon's chatty assistant to the world. The Echo features prominently in Amazon's Alexa ads, and its basic structure has informed the design of every other so-called smart speaker on the market. The Echo Dot has been the best-selling Alexa device since its debut. It was Amazon's best-selling device, period, during the 2016 holiday season, and the company just announced that yesterday, the Echo Dot was also the most popular item on Prime Day.
