Explanation

IBM revolutionized the micro-computer industry in 1981 with the IBM Personal Computer (PC), which established the de facto standard for PCs. Apple existed earlier (Apple II in 1977) but IBM's entry legitimized personal computers for business use. DELL and Microsoft became prominent later.
