Company mortality versus lifetime (Daepp, et al. 2015).[1]
The mortality function closely follows an exponential curve based on a constant hazard rate.

• The IBM 701 Commercial Computer, introduced in 1952, was the first mass-produced large-scale electronic computer.
• The IBM 650 Magnetic Drum Data-Processing Machine, also introduced in 1952, was a popular intermediate-sized electronic computer for scientific and business applications.
• The IBM 350 disk storage unit, introduced in 1956, was the first magnetic hard disk for data storage. It stored five million six-bit characters on fifty-two 24-inch diameter disks. The storage capacity was 3.75 megabytes.
• IBM embraced FORTRAN as a programming language in 1957.
A diode-transistor-logic (DTL) NAND gate built from a PNP transistor in 1959.
As can be seen, IBM had an unique way of representing transistors at that time.

• IBM introduced The IBM 1401, the first mass-produced transistorized computer in 1959. It featured a magnetic core memory and stored program capability.
• The IBM System/360 was announced on April 7, 1964. It was a configurable general purpose mainframe computer system that used interchangeable software and peripherals, such as printers and magnetic tape data storage. The System/360 became the dominant mainframe computer of its time.
A keyboard that only a mathematician would love. This is the layout of the IBM APL keyboard. APL was the timeshare interpretive programming language of the IBM System/360 and System/370. APL was principally created by computer scientist, Kenneth E. Iverson (1920-2004). (Via Wikimedia Commons.)
The announcement of the System/360 was coincident with the invention of vaporware. Some System/360 components in publicity photographs were actually wooden mockups. There was a popular joke about this in technology circles - "Why do women avoid marrying IBM salesmen? In the first year of marriage, the salesmen just sit at the side of the bed and explain how wonderful it will be when it finally happens."
• IBM invented the one-transistor dynamic random-access memory (DRAM) memory cell in 1966.
• To defuse some of its antitrust problems, IBM unbundled software and services from its hardware in 1969.
• IBM announced its System/370, the successor to System/360, in 1970. As a consequence of the popularity of its System/360 and System/370 mainframes, IBM sold 80% of computers in the U.S., and 70% of computers worldwide in the 1960s and 1970s.
• IBM introduced relational databases in 1970.
• Just after Watson's departure, the IBM Personal Computer was introduced in 1981. This event proved more of a boon to Microsoft and PC-compatible manufacturers than to IBM. IBM sold its personal computer business to Lenovo, a Chinese company, in 2005.

• The United States antitrust lawsuit against IBM was dismissed in 1982 as being without merit. This suit was initiated in 1969, and it spawned another popular joke in its early years - "An IBM engineer invented a time machine. To prove that it worked, he travelled to a date in the far future. When he returned, his colleagues asked him about the first thing he did in the future. He responded that he bought a newspaper to check the status of the IBM antitrust lawsuit."Beginning in the 1990s, IBM began downsizing operations, divesting some operations, such as its personal computer division, and concentrating on computer services, software, supercomputers, and scientific research. In 2001, IBM became the first company to produce more than 3,000 patents in one year; and, in 2008 achieved 4,000 patents. In its lifetime, IBM has been issued more than 150,000 patents. Among its innovations, IBM introduced the floppy disk, the magnetic stripe card as found on credit cards, and the Universal Product Code (UPC) barcode. IBM scientists arranged 35 xenon atoms in a scanning tunneling microscope to spell "IBM" in 1990. IBM has had five Nobel Physics Laureates that include Leo Esaki (b. 1925) in 1973 for his invention of the tunnel diode, Gerd Binnig (b. 1947) and Heinrich Rohrer (1933-2013) in 1986 for the scanning tunneling microscope, and Georg Bednorz (b. 1950) and Alex Müller (1927-2023) in 1987 for the discovery of high temperature superconductors.
• In 1998, IBM introduced the first microprocessor with a GHz clock rate.
