Everyone has heard about the success of the young Californian company Oculus, which develops the world's best virtual reality glasses. It’s not surprising, because before this, virtual reality seemed like just a plot for science fiction films of the 80s and caused skeptical grins. The appearance of the world's first VR glasses with a viewing angle of 110 degrees, compact and relatively inexpensive, thundered like an explosion and forced the largest manufacturers to turn their gaze towards virtual reality. The author of the best-selling book “Console Wars,” Blake J. Harris, vividly and interestingly outlined his version of the dizzying rise and no less dizzying fall of the Oculus company and its creator, a self-taught genius, a charming geek and a big fan of Donald Trump. The publishing layout of the book is saved in PDF A4 format.
