IBM started a personal computer craze in 1981 with the personal computer, a large bulky box capable of reading floppy disks and stuffed with 64 kilobytes of RAM. Of course, technology obsolesces as quickly as current download speeds, but having the ability to own (and purchase) the revolutionary machines led to a drop in typewriter sales and other 1970s technology. The next classic celebrating a big birthday: the NES, which will turn 35 in less than two years.
