Amazon’s busy quarter was headlined by its biggest devices event yet and a record-setting Prime Day. Last month, Amazon unveiled 13 new devices?— including everything from subwoofers and amplifiers to an Alexa-powered microwave — as well as a flurry of?new Alexa-related software capabilities,?developer tools?and other features at an event at its Seattle HQ.

Amazon’s standard Prime subscription rate is 9/year, which would translate into revenue of more than .8 billion, although the company offers discounted memberships for students and others.
