In the late 1970s, minicomputer technology gave way to personal computers and relatively low-cost computers were becoming mass market commodities, allowing businesses to provide their employees access to computing power that ten years before would have cost tens of thousands of dollars.

This proliferation of computers created a ready market for interconnecting networks and the popularization of the Internet.
