Watching movies at the cinemas in 3D can be a wholesome and exciting experience, but in the technological world, this happens to be an old technology. Virtual Reality (or VR as it is colloquially called) is currently making waves and is the new kind of cool, cooler than the hover-board. Virtual Reality is like a modern calculator that makes 3D experience appear like the Abacus.
The front-runners of the technology are Facebook and Google with their Occulus and Cardboard respectively although there are other tech giants and startups also in the VR technology.
