Google Chromecast HDMI dongle arrives to rival Apple TV

Google unveiled Chromecast on Wednesday, a device that looks set to rival Apple TV.

Google Chromecast, essentially little more than an HDMI dongle, is Google's first foray into the media streaming market, and it works in a similar way to Apple TV and the firm's Airplay technology.

Google showed off the Chromecast dongle, which measures little more than 2in, at an event in San Francisco on Wednesday. Google explained, "With Google Chromecast, all you have to do is plug it into any HDMI input on your TV, connect to your home WiFi network, and you're ready to kick back and watch. It simply disappears behind your TV.
