Chromecast, Google’s popular $35 dongle that plugs into your TV’s HDMI port, letting you stream video and music to your television, received a number of updates today, Google announced this morning at its I/O developer conference. The most notable updates include support for mirroring your Android device’s screen to your TV, a new, interactive background display feature called “Backdrop” and support for streaming from device to TV even when you’re not on the same wireless network.

Google says it has been “blown away” by Chromecast’s performance, which is now outselling every other streaming device, the company claims. That’s likely due to its low price point, which makes experimenting with Chromecast more of “oh, why not?” kind of purchase, rather than a thoughtfully considered investment, like rival Apple TV.
