In the 1940s and 1950s, IBM began its initial forays into computing, which constituted incremental improvements to the prevailing card-based system. A pivotal moment arrived in the 1960s with the introduction of the System/360 family of mainframe computers.

These are the stories of the people, innovations and values that have defined IBM for over a century, and the tales of how IBM helped pioneer the information technology industry.

IBM mainframes run operating systems supplied by IBM and by third parties. The operating systems on early IBM mainframes have seldom been very innovative, except for TSS/360 and the virtual machine systems beginning with CP-67.

IBM mainframes are large computer systems produced by IBM since 1952. During the 1960s and 1970s, IBM dominated the computer market with the 7000 series and the later System/360, followed by the System/370. Current mainframe computers in IBM's line of business computers are developments of the basic design of the System/360.

IBM began as the Computing-Tabulating-Recording Co. (C-T-R), a corporation composed of three companies that manufactured tabulating machines, scales, and time recorders. In 1914, Thomas J. Watson Sr. joined C-T-R as general manager. He became president in 1915 and C-T-R was renamed IBM shortly afterward.

On August 12, 1981, Estridge unveiled the IBM PC at New York’s Waldorf Hotel. Priced at USD 1,565, it had 16 kilobytes of RAM and no disk drive, and it came with two programs — VisiCalc, for producing spreadsheets, and EasyWriter, for word processing. To add a display, two diskette drives, and a printer cost nearly USD 3,000 more.
