Amazon introduced its Echo device in 2014, a home speaker with a virtual assistant, Alexa, built in. The initial pitch of the Echo was a way to control your music using just your voice.
In 2019, the Echo can do a lot more than play music: The device can act as a smart home hub and a way to shop on Amazon, as well as the brains behind an entire household's operations. Alexa can supply your calendar, add items to your shopping list, answer random queries, and more.
Plus, Amazon has since introduced an entire lineup of Echo devices, like the Show with a built-in screen, the Studio for high-end audio, and the Dot for making your home "smart" in every room.
