2013-2015

When Google launched these »smart glasses« with a built-in camera, voice controls and a revolutionary screen, expectations were sky high. Technology enthusiasts paid $1,500 for this futuristic gadget, and all the attention it got made everyone think that it was a fully developed product. However, it was nothing more than an expensive prototype, and one that did not meet the needs of its users. The technology didn’t quite work. The built-in camera raised concerns about privacy issues. People did not like the idea of being filmed at any time and place, and Google Glass was banned in several places. Users began to be called »Glassholes.«
