15 years go this week the CEO of Sony announced that the next big trend in TV would be 3D. 3D TVs landed in stores in 2010 but quickly fell out of favor. The need for special, often uncomfortable glasses and a lack of interesting content contributed to their decline. Competition from more appealing technologies like 4K and HDR TVs further pushed 3D TVs into obsolescence. By 2017, major manufacturers stopped making them.
