When did Americans begin using computers in their homes and small businesses?

C. The 1980s took the test and it is correct

The adoption of personal computers in a big scale began with the microcomputer revolution of the eighties decade. It started with the launch of IBM's Personal Computer (or PC). This product was aimed to be used by a single individual as the end user. This was a big difference in comparison to mainframe computers, where an individual would normally submit a request for information that would be processed by a team in charge of operating the computer. Personal computers were initially used by hobbyists and technicians, and as the cost of the microprocessor started going down with the years, they became affordable for the majority of households in the country.
