Lifespan: Never actually made it to consumers
What it did: Google's Nexus Q was a streaming video player that made it possible to play YouTube and Google Music on a TV — kind of an early predecessor to the Google Chromecast, Roku, and Amazon Fire TV devices that are so popular today. It sported a funky, spherical design.
The product was unveiled at Google's 2012 I/O developers' conference, and given to attendees. However, it was slated to retail for a whopping $299, which reviewers including The New York Times' David Pogue slammed as way too expensive for its very limited functionality. Google decided to discontinue the Nexus Q before it was ever sold publicly.
