Since the first-generation Echo, customers have purchased more than 100 million Alexa-enabled devices.

Judge as of April 2019. True: Amazon disclosures (shareholder letter, official press releases or executive statements recorded by reliable press as company figures) or credible independent counts show cumulative customer purchases of Alexa-enabled devices (Echo and other Amazon devices with Alexa built in, as Amazon counts them) of more than 100 million by early 2019, since the first Echo in 2014. Mostly true: the total is about 100 million (for example 'about 100 million' rather than clearly above), or it reaches 100 million only when third-party devices with Alexa are counted in a way Amazon's own counting allowed. Mixed: not applicable unless the evidence is split; use only if credible sources disagree roughly evenly. Mostly false: the 100 million figure is reached only by counting something broader than purchases (for example devices shipped to channels, or app installs), or it was reached only after April 2019. False: credible data show cumulative Alexa-enabled device sales clearly below 100 million (for example under about 80 million) as of April 2019.

Set before the research began.

4. E4 More than 100 million Alexa devices have been sold | TechCrunch TechCrunch · 4 January 2019

   “More than 100 million devices with Amazon’s Alexa assistant pre-installed have been sold, the company said Friday.”

The Verge, PCMag and TechCrunch all reported in early January 2019, before the April 2019 claim, that Amazon said more than 100 million Alexa-enabled devices had been sold, with The Verge and PCMag attributing the figure to SVP Dave Limp (E1, E3, E4). However, an Amazon spokesperson told PCMag that this figure includes third-party products with Alexa built in as well as Amazon-branded devices (E2). None of the evidence gives a breakdown showing that Amazon's own devices alone passed 100 million. The total therefore matches the criteria's "mostly true" case: it reaches 100 million when third-party devices are counted the way Amazon counts them.
