IBM

International Business Machines Corp

A giant of the technology world, IBM builds hybrid cloud and AI platforms, software, servers, storage, and consulting services used by businesses and governments everywhere. It began in 1911 as the Computing-Tabulating-Recording Company, which made punch-card tabulators, time clocks, and weighing scales; in 1924 Thomas Watson renamed it International Business Machines. Fun fact: it's nicknamed "Big Blue" after its blue mainframe cabinets, and its Watson AI famously beat human champions on the quiz show Jeopardy!.
