IBM Corp. (previously named the "International Business Machines Corporation") "was incorporated on February 24, 1924. . . . Before its entry into the electronic data processing (EDP) industry, IBM manufactured punched card accounting machines and other products. In addition to its EDP business, IBM develops, manufactures, and markets other business machines, including copiers, dictating equipment, and electric typewriters. IBM has been deeply involved in the phenomenal growth of the electronic data processing industry since almost the beginning of the industry.”
“IBM is one of the largest industrial corporations in the world. It achieved technical leadership in the computer industry over other early entrants, such as Sperry Rand, in the mid-1950’s and thereafter pioneered the development of many electronic data processing products. . . .” 
It "is both a hardware and a software company. On the hardware side, IBM manufactures and licenses, among other things, Intel-compatible PCs. On the software side, IBM develops and sells, among other things, Intel-compatible PC operating systems and office productivity applications.”
