IBM was founded in 1911 as the Computing-Tabulating-Recording Company (CTR), a holding company of manufacturers of record-keeping and measuring systems. It was renamed "International Business Machines" in 1924 and soon became the leading manufacturer of punch-card tabulating systems. During the 1960s and 1970s, the IBM mainframe, exemplified by the System/360 and its successors, was the world's dominant computing platform, with the company producing 80 percent of computers in the U.S. and 70 percent of computers worldwide.11 Embracing both business and scientific computing, System/360 was the first family of computers designed to cover a complete range of applications from small to large.12
IBM entered the microcomputer market in 1981 with the IBM Personal Computer; its architecture remains the basis for the majority of personal computers sold today.13 The company later also found success in the laptop space with the ThinkPad. Since the 1990s, IBM has concentrated on computer services, software, supercomputers, and scientific research; it sold its microcomputer division to Lenovo in 2005. IBM continues to develop mainframes, and its supercomputers have consistently ranked among the most powerful in the world in the 21st century.
As one of the world's oldest and largest technology companies, IBM has been responsible for several technological innovations, including the Automated Teller Machine (ATM), Dynamic Random-Access Memory (DRAM), the floppy disk, Generalized Markup Language, the hard disk drive, the magnetic stripe card, the relational database, the SQL programming language, and the Universal Product Code (UPC) barcode. The company has made inroads in advanced computer chips, quantum computing, artificial intelligence, and data infrastructure.141516 IBM employees and alumni have won various recognitions for their scientific research and inventions, including six Nobel Prizes and six Turing Awards.17
