Exactly 12 months ago, Google unveiled its Chromecast streaming dongle for the first time. To celebrate its first anniversary, Google is offering all Chromecast owners a 90-day free trial for Google Play Music All Access, its premium music streaming service.

The offer is available now in the US and can be redeemed up until September 30, 2014. To grab the free subscription, you’ll need to head here; it’s unclear whether this offer stretches to other territories, however.

To put the icing on the cake, Google today revealed that Chromecast users have hit the ‘Cast’ button 400 million times in total. It’s not sharing any sales numbers for the device, but that’s hardly suprising given its secrecy around Nexus sales. Still, it gives us some idea as to the popularity of Chromecast and suggests that people who do own the device are using it fairly regularly.
