The company has driven innovations including FORTRAN, SQL, DRAM, the hard disk drive, floppy disk, ATM, and UPC barcode, while leading in supercomputing—such as Deep Blue’s chess victory—and holding records for U.S. patents for decades. Today, IBM focuses on hybrid cloud computing, artificial intelligence via Watson, quantum computing with systems like IBM Q System One, cybersecurity, data analytics, and IoT, supported by the world’s largest industrial research organization across 19 facilities in 12 countries.
