IBM, or International Business Machines, was a manufacturer of computing hardware and software. Sometimes known as Big Blue, they created the first commercially-sucessful and affordable computer, the IBM 1401, in 1959 (sometimes known as the "Model T Ford" of computers.)
In 1981, IBM released the first Personal Computer, which introduced Microsoft into homes around the country. IBM's PC was successful enough to be replaced with the PC-XT (1983), PC-AT (1984), PCjr (1984), and PC Convertible (1986.) The PC line was replaced with the Personal System/2 (PS/2) line in 1987, which was manufactured until the early 1990s.
In 1992, IBM released another important computer which would change the world of computing. The ThinkPad was released as a replacement for the IBM PS/2 portable machines introduced in 1989. Later in the 1990s, IBM joined the "AIM Alliance" to create the PowerPC processor architecture, working with Apple Computer and Motorola. The PowerPC processor was found in several gaming consoles, Macintosh computers, and other devices.
Today, IBM's focus has shifted from hardware to software. IBM still manufactures mainframe machines, but their focus is in Watson, the IoT (Internet of Things), and the cloud. IBM handed their hardware business over to third-party companies, mainly Lenovo. Lenovo, a Chinese manufacturer of computers, still manufactures the ThinkPad, ThinkCentre, and ThinkServer lines originally introduced by IBM.
Over the years, IBM developed significant inventions and innovations which have changed our lives. Here is a list of just a few of those innovations:
