It's been one of the more conspicuous omissions in the media hub space: despite Google Play being the cornerstone of Google's content strategy, you couldn't truly use the company's music or movie services through Google TV without depending on content you'd already paid for elsewhere. As of a new upgrade, the ecosystem has come full circle. Viewers with Google TV boxes can at last buy or rent directly from Google Play Movies and Google Play Music, and the content will be indexed in the TV & Movies section alongside third-party video services and traditional TV. The upgrade also helps Google's TV front end play catch-up with its mobile counterpart by adding automatic app updates and subscriptions. While device owners may have to wait a few weeks as the upgrade rolls out, the addition signals a big step forward for a platform that has normally leaned heavily on others for help.
