Alexa will talk you into loving Amazon

Amazon's Alexa was showered with attention at last month's CES tech show in Las Vegas, as dozens of companies invited the voice assistant to live in their cars, washing machines and set-top boxes. Yet, behind all that luster is a somewhat uncomfortable question about Amazon's 2-year-old artificial intelligence platform: Does Alexa make Amazon any money? The answer, say several analysts: No, but it will. And when it does, it'll be huge. As part of Amazon's fourth-quarter earnings report on Thursday, the company mentioned that Alexa-powered devices were Amazon's top-selling products this holiday season.
