April 1952: US IBM introduces the IBM 701, the first computer in its 700 and 7000 series of large scale machines with varied scientific and commercial architectures, but common electronics and peripherals. Some computers in this series remained in service until the 1980s. June 1952: US
The history of the personal computer as a mass-market consumer electronic device began with the microcomputer revolution of the 1970s. A personal computer is one intended for interactive individual use, as opposed to a mainframe computer where the end user's requests are filtered through operating staff, or a time-sharing system in which one large processor is shared by many individuals.
