At Google I/O the Chromecast sales figure was put at 25 million for the US$35 dongle, but a little over 2 months later Google has let slip a more up to date figure of over 30 million Chromecasts sold.
The figure was mentioned by Google CEO Sundar Pichai during the Alphabet Q2 earnings call this morning, in response to a question regarding Google’s hardware strategy, saying ‘We now have over 30 million Chromecast devices sold’.
The question highlighted that Google takes Chromecast seriously and uses their own in-house developed/built hardware such as Google Pixel and Nexus as a driver of the various eco-systems they produce such as Android, ChromeOS and obviously Google Cast.
