As @lajamerr tries to clear up, "chromecast" has now fallen victim to google's incredulous renaming/rebranding tradition.

Chromecast is now either the action you take to "beam" from your handheld device to a TV or an AndroidTV/GoogleTV/Chromecast hybrid device.

Just went to the google store to find a link for you and had some trouble finding what I'm talking about and apparently chromecast devices are now considered part of the Nest family complicating things even more.

Edit: I stand somewhat corrected... there still is a chromecast device that comes without AndroidTV. I guess this just further illustrates my point about how bad/confusing google's naming and branding strategy is.
