But now there's a new startup called OUYA that could give all three of them a run for their money.

OUYA is a $99 Android-powered box that's open to any developer for hacking. That means you can crack it open and play with the hardware and develop any kind of Android application for a television.

OUYA is starting as a Kickstarter project, looking to raise nearly $1 million to get it off the ground. Any extra money goes toward helping developers create games for the platform.

Given how open the platform is, it's sure to be a hit with developers who are always very appreciative when they find new hardware and software they can muck around with and turn into their own.

For example, when the Xbox 360's Kinect motion controller first came out, there were a bunch of hacks for it — though Microsoft didn't endorse them.
