Remember CD-ROMs? Those were the days, ey? You had to put a spinning disc in the front of your PC to install the games you physically bought and paid for. Actually, in the case of the Quake shareware CD-ROM, it was stuffed full of games you didn't buy, too.
That's according to Fabien Sanglard, who's written a blog post on the curious case of the Quake shareware CD release. The game itself took up a mere 22 MB of a CD-ROM's 640 MB capacity, leading John Carmack to joke that if there was ever a CD version of Doom, it would come with a "Making of Doom" feature film to use up the entire capacity.
