It's suddenly become newsworthy that Google Home, the company's "first" smart home product, uses the brain of Chromecast to function. But why? We've already showed you the source of that information - not that it matters all that much. Google has been working on this same project for years - it's just had a different name at its different levels of inception. It was (and is) part of the Google On community, which runs Weave connections to other Brillo devices, which are related to Chromecast, which was originally called Nexus Q. It's all part of the same initiative.
