How Amazon is making Alexa more than a household name

Stephen Whiteside

Artificial intelligence (AI) is largely about potential.

But after approximately 18 months on the general market in the US, Alexa - an AI-driven digital assistant from Amazon which understands, analyzes and replies to natural language, and is best known for powering the brand's Echo, Dot and Tap interactive speakers - is also about revenue.

Although Amazon has not released official sales figures for the Echo, insights firm Consumer Intelligence Research Partners estimates that over 5.1 million devices have been sold to date. NPD, another research provider, further reported that owners of the speaker spent 10% more on in the first six months after acquiring the product, with purchase frequency rising 6%.
