I'm compiling a list of "Hot technologies" that had a pretty sudden fall (classic Gartner Hype Cycle):
* Blockchain
* 3D Printing
* Nanotechnology
* Internet of Things
* Cloud Gaming
* VR/AR
* 3D TV
* Quadrophonic Stereo

Note: Non of these "failed". They have found uses, it's just that their rollout was FAR less than the crazy hype they generated. (e.g. People thought they'd soon be 3D printing an iPhone)

Is there anything you'd add to this list? (or just a comment?)
