The dramatic rise of Apple during the reign of Steve Jobs, which unfortunately ended recently, is truly commendable. I remember seeing a Mac for the first time when I was in graduate school. At that stage, the Mac was used mostly by the Administrative staff at the University. Later, when I joined the workforce, I realized that Macs were used by the Administrative staff, the Technical Publications groups, and the Marketing and Sales teams within most organizations, while everyone else used PCs or Unix machines.
At this point, Steve Jobs was CEO of two private companies, NeXT Computer and Pixar, while Apple was struggling under various CEOs. While Apple experimented with management changes at the top, it lost its edge in the marketplace as PCs dropped in price and gained traction. Slowly, many corporations stopped buying Macs altogether. IT departments preferred to stick with one platform as far as possible, and that was Microsoft Windows on PCs.
