A quarter century ago, a new package called Windows faced some pretty daunting competition.
Microsoft shipped Windows 1.0 on November 20th, 1985. Twenty-five years later, it’s not just hard to remember an era in which Windows wasn’t everywhere–it’s also easy to forget that it wasn’t a given that it would catch on, period.
The company had announced the software in November of 1983, before most PC users had ever seen a graphical user interface or touched the input device known as a mouse. But by the time Windows finally shipped two years later, after a series of embarrassing delays, it had seemingly blown whatever first-mover advantage it might have had. At least four other major DOS add-ons that let users run multiple programs in “windows” had already arrived.
