That’s how much, according to Statista. By 2022, it’ll be almost double that. > The obvious leader in all this — the company that owns a significant share of that smart-home industry — is Amazon, which has reportedly sold 100 million Alexa devices. Google, which sells a whole collection of Google Assistant-supporting home devices, controls another chunk. The two companies are locked in a battle for the heart and soul of your smart-home experience, with Apple’s HomeKit standing off to the side. Many smart-home devices were on display at CES 2019, but the tech conference did little to clarify which company is on the path to total market dominance.
