Every now and again, the video game industry evolves in often unimaginable ways. Some of those evolutions stick while others eventually fall by the wayside. After the success of the Nintendo Wii, we assumed that the movement sensor evolution was one that would be here to stay. The addition of Xbox Kinect and PlayStation Move was conclusive proof that wouldn't be the case.

Nintendo's rivals did not enjoy the same amount of success with their movement technology as the Wii did. At last count, the Wii was the fifth best-selling console of all time, racking up an incredible 101 million units sold. While many of us still play our Wiis to this day, what's become of all those misbegotten Kinects?

Well, turns out a few of them have been above travelers' heads at Newark Liberty International Airport. Video game historian Jason Scott recently noticed the Kinects during a visit to the airport and posted photos on Twitter. Upon closer inspection, you can clearly see the Xbox logo still stamped on them.

Curiously, the Newark airport isn't the only establishment that uses the devices as security cameras. Eight months ago, Walmart was discovered to be doing the exact same thing.

It turns out the Kinect actually hung around for far longer than we realized, pun very much intended. The Xbox's motion sensor wasn't entirely discontinued until 2017, according to IGN, and it's only the latest version of the Xbox One that doesn't include a port for it.

As for why Newark airport and Walmart chooses to use Kinects for its surveillance systems, that remains unclear. They must provide a pretty clear image. Otherwise, why would they go to so much trouble to buy them up? Only trouble is, where will these places go if their Kinects break? Perhaps they need to strike up some sort of deal with Microsoft, or maybe they already have one in place.
