Alexa helps propel Amazon to another massive quarter

Amazon has been pretty busy the past few months, unleashing a slew of new hardware just in time for the holiday season. Several of those products haven't made it to market quite just yet, but that hasn't stopped the company from raking in money as per usual. In its third quarterly earnings report, Amazon reported that net sales in the past three months have totaled $56.6 billion, which is a 30 percent year-over-year increase. Meanwhile, net income has increased to $2.9 billion in the third quarter, which is a big jump from the $256 million from this time last year. This is the 14th straight quarter that the online retail giant has reported a profit. That said, the numbers are below Wall Street estimates and the stock dropped by 6 percent as earnings came in.
