Fire up the Google Cast app – which is used to discover content to stream on Chromecast-connected TVs and speakers, and to manage them – and you’ll spot a message indicating that it’s getting a new name: Google Home.
The rebranding makes sense, as Google officially launched a new voice-activated speaker (also called Home – yup, it’s kinda messy) at its hardware launch event yesterday and will need an app to manage it.
