What Does Ibm Stand for? the Complete Guide to Its Meaning, History, and Products
Under Watson Sr. and later his son, Thomas Watson Jr., IBM transformed from a tabulator manufacturer into an electronic computing powerhouse. During the Great Depression, while competitors laid off staff and curtailed production, Watson Sr. kept assembly lines running, stockpiling machines and paper stock in warehouses. That gamble paid off when the US Congress passed the Social Security Act of 1935. The federal government needed to track employment and tax data for 26 million workers immediately, and IBM was the only supplier with sufficient inventory to fulfill the mandate.
By the 1950s, electronics were replacing mechanical gears. Vacuum tubes gave way to transistors, leading to the development of the company's first digital computers: the IBM 701 in 1952 and the magnetic-drum IBM 650 in 1953. Yet customers faced a frustrating problem: every computer model ran distinct software, requiring companies to rewrite their entire codebase whenever they upgraded hardware.
In April 1964, Thomas Watson Jr. announced the System/360 architecture. The project cost $5 billion, more than the federal government spent on the Manhattan Project, and introduced a family of compatible computers that used the same peripheral equipment and operating code across small and large configurations. System/360 established the 8-bit byte as an industry standard and cemented IBM's role as a commercial computing pioneer.
