The System/360 Revolution

  • Gerard O’Regan


The IBM System/360 was a family of mainframe computers designed and developed by IBM. It had a major impact on the computing field, and it set IBM on the road to dominate the field for the next 20 years, up to the development of personal computers in the early 1980s. It was the beginning of an era of computer compatibility, where machines across a product line could work with each other. It meant that IBM customers could start off with a low specification member of the 360 family to meet its current needs, and then as its needs evolved over time, it could upgrade to a more powerful member. It was a massive $5 billion investment (bet the business gamble) by Thomas Watson Jr., and it moved IBM from its traditional business and product lines into the unknown with the gamble that the future would be the System/360.
