Google has had hits and misses as a hardware company, but its Chromecast dongle has been a big hit in the US. It plugs into the USB socket of TVs, and then streams videos, music and apps from nearby devices – Android, mainly, but supporting iOS and laptops/computers too. The device went on sale in the UK this morning for £30, as part of a global rollout that’s also seen it made available in France, Germany, Spain, Italy, Netherlands, Norway, Sweden, Denmark and Finland. For now, it supports Google services including YouTube, Google Play Music and Google Play Movies, as well as third-party apps including Netflix and the BBC. Pandora, Songza and Vevo are the music apps supporting Chromecast at the moment, albeit the first two of those are only available in its North American markets.
