Amazon seemingly didn’t realize what it had on its hands with the original Echo. Released five and a half years back for a select number of Amazon Prime users, the first Alexa device ushered in a consumer electronics revolution.

According to numbers from Canalys, 26.1 million smart speakers were shipped in Q2 2019. That’s a hefty 55.4% growth from the year prior, with Amazon capturing just over a quarter of the total global market. Much of Amazon’s growth (up 61% y-o-y) is courtesy of its rapidly growing line, which now ranges from the $50 Echo Dot to the $200 Echo Studio.
