The film’s financial success and superb use of 3D paved the way for the 3D films that would follow, and it no doubt convinced the major TV manufactures, content creators and broadcasters that 3D TV would be equally popular in the home. The 3D debut of this technology was James Cameron’s movie Avatar. This made capturing, reproducing, and displaying 3D content far easier than with film. In the cinemas this technology was digital cinemaphotography. The 2009 3D boom was enabled by the convergence of several technologies. Our brains then process these two video feeds and calculates the differences between them, which we perceive as stereoscopic vision with depth perception. It achieves this via stereoscopy – feeding the left and right eyes slightly offset versions of the same image. So, how does 3D work anyway? Essentially, 3D is an optical illusion that aims to trick the brain into perceiving a flat two-dimensional (2D) image as a three-dimensional (3D) image with depth. This led Samsung to drop support for 3D TVs in 2016, with all other major manufacturers doing likewise in 2017.
Neither market share nor units sold expanded greatly beyond 2012’s levels, and sales dropped sharply from 2015 onwards. Suffice to say, these predictions were wrong.
