Thanks, Alexa: Amazon's net sales increased 38% to $60.5 billion in Q4 2017. That’s compared with $43.7 billion in the same period of 2016. The ecommerce giant’s smart speaker device is likely one of the causes. “Our 2017 projections for Alexa were very optimistic, and we far exceeded them. We don’t see positive surprises of this magnitude very often—expect us to double down,” said Jeff Bezos, Amazon founder and CEO, in a statement.
