punch-card tabulating systems. During the 1960s and 1970s, the
IBM mainframe, exemplified by the
System/360 and its successors, was the world's dominant
computing platform, with the company producing 80 percent of computers in the U.S. and 70 percent of computers worldwide.
Embracing both business and scientific computing, System/360 was the first family of computers designed to cover a complete range of applications from small to large.

History
1910s–1950s
IBM originated with several technological innovations developed and commercialized in the late 19th century. Julius E. Pitrap patented the computing scale in 1885; Alexander Dey invented the dial recorder (1888);
Herman Hollerith patented the
Electric Tabulating Machine (1889); and
Willard Bundy invented a
time clock to record workers' arrival and departure times on a paper tape (1889). On June 16, 1911, their four companies were
amalgamated in New York State by
Charles Ranlett Flint forming a fifth company, the
Computing-Tabulating-Recording Company (CTR) based in Endicott, New York.
The five companies had 1,300 employees and offices and plants in Endicott and
Binghamton, New York;

Collectively, the companies manufactured a wide array of machinery for sale and lease, ranging from commercial scales and industrial time recorders, meat and cheese slicers, to tabulators and punched cards.
Thomas J. Watson, Sr., fired from the
National Cash Register Company (NCR) by
John Henry Patterson, called on Flint and, in 1914, was offered a position at CTR.
Watson joined CTR as general manager and then, 11 months later, was made President when
antitrust cases relating to his time at NCR were resolved. Having learned Patterson's pioneering business practices, Watson proceeded to put the stamp of NCR onto CTR's companies.
He implemented sales conventions, "generous sales incentives, a focus on customer service, an insistence on well-groomed, dark-suited salesmen and had an evangelical fervor for instilling company pride and loyalty in every worker".
His favorite slogan, "
THINK", became a mantra for each company's employees.
During Watson's first four years, revenues reached $9 million ($ today) and the company's operations expanded to Europe, South America, Asia and Australia.
Watson never liked the clumsy hyphenated name "Computing-Tabulating-Recording Company" and chose to replace it with the more expansive title "International Business Machines" which had previously been used as the name of CTR's Canadian Division;
[Belden (1962) p. 125] the name was changed on February 14, 1924. By 1933, most of the subsidiaries had been merged into one company, IBM.

made extensive use of Hollerith punch card and alphabetical accounting equipment and IBM's majority-owned German subsidiary, Deutsche Hollerith Maschinen GmbH (
Dehomag), supplied this equipment from the early 1930s. This equipment was critical to Nazi efforts to categorize citizens of both Germany and other nations that fell under Nazi control through ongoing censuses. These census data were used to facilitate the round-up of Jews and other targeted groups, and to catalog their movements through the machinery of the
Holocaust, including internment in the concentration camps. Black contends that IBM's dealings with Nazis through its New York City headquarters persisted during World War II. Nazi concentration camps operated a Hollerith department called Hollerith Abteilung, which had IBM machines, including calculating and sorting machines.
IBM as a military contractor produced 6% of the
M1 Carbine rifles used in World War II, about 346,500 of them, between August 1943 and May 1944. IBM built the
Automatic Sequence Controlled Calculator, an electromechanical computer, during World War II. It offered its first commercial stored-program computer, the vacuum tube based
IBM 701, in 1952. The
IBM 305 RAMAC introduced the hard disk drive in 1956. The company switched to transistorized designs with the
7000 and
1400 series, beginning in 1958. In which, IBM considered the
1400 series the
''model T'' of computing, because it was the first computer with over ten thousand unit sales by IBM.
In 1956, the company demonstrated the first practical example of

when
Arthur L. Samuel of IBM's
Poughkeepsie, New York, laboratory programmed an
IBM 704 not merely to play checkers but "learn" from its own experience. In 1957, the
FORTRAN scientific programming language was developed.
1960s–1980s
In 1961, IBM developed the
SABRE reservation system for
American Airlines and introduced the highly successful
Selectric typewriter.
Also in 1961 IBM used the
IBM 7094 to generate the first song sung completely by a computer using synthesizers. The song was Daisy Bell (Bicycle Built for Two).
In 1963, IBM employees and computers helped NASA track the orbital flights of the
Mercury astronauts. A year later, it moved its corporate headquarters from New York City to
Armonk, New York. The latter half of the 1960s saw IBM continue its support of space exploration, participating in the 1965
Gemini flights, 1966 Saturn flights, and 1969 lunar mission. IBM also developed and manufactured the
Saturn V's Instrument Unit and

On April 7, 1964, IBM launched the first computer system family, the
IBM System/360. It spanned the complete range of commercial and scientific applications from large to small, allowing companies for the first time to upgrade to models with greater computing capability without having to rewrite their applications. It was followed by the
IBM System/370 in 1970. Together the 360 and 370 made the
IBM mainframe the dominant

and the dominant computing platform in the industry throughout this period and into the early 1980s. They and the operating systems that ran on them such as
OS/VS1 and
MVS, and the middleware built on top of those such as the
CICS transaction processing monitor, had a near-monopoly-level market share and became the thing IBM was most known for during this period.
In 1969, the United States of America alleged that IBM violated the
Sherman Antitrust Act by monopolizing or attempting to monopolize the general-purpose electronic digital computer system market, specifically computers designed primarily for business, and subsequently alleged that IBM violated the antitrust laws in IBM's actions directed against leasing companies and plug-compatible peripheral manufacturers. Shortly after, IBM unbundled its software and services in what many observers believed was a direct result of the lawsuit, creating a competitive market for software. In 1982, the Department of Justice dropped the case as "without merit".
Also in 1969, IBM engineer
Forrest Parry invented the
magnetic stripe card that would become ubiquitous for credit/debit/ATM cards, driver's licenses, rapid transit cards and a multitude of other identity and access control applications. IBM pioneered the manufacture of these cards, and for most of the 1970s, the data processing systems and software for such applications ran exclusively on IBM computers. In 1974, IBM engineer
George J. Laurer developed the
Universal Product Code. IBM and the

IBM entered the
microcomputer market in the 1980s with the
IBM Personal Computer (IBM 5150). The computer, which spawned a
long line of successors, had a profound
influence on the development of the personal computer market and became one of IBM's best selling products of all time. Because of a lack of foresight by IBM, the PC was not well protected by

compatible competitors in the PC market.

. Following a dispute, Microsoft severed the collaboration and IBM continued development of OS/2 on its own but it failed in the marketplace against Microsoft's
Windows during the mid-1990s.
1990s–2000s
In 1991 IBM began spinning off its many divisions into autonomous subsidiaries (so-called "Baby Blues") in an attempt to make the company more manageable and to streamline IBM by having other investors finance those companies. These included
AdStar, dedicated to disk drives and other data storage products; IBM Application Business Systems, dedicated to mid-range computers; IBM Enterprise Systems, dedicated to mainframes; Pennant Systems, dedicated to mid-range and large printers;
Lexmark, dedicated to small printers; and more. Lexmark was acquired by
Clayton & Dubilier in a
leveraged buyout shortly after its formation.
In September 1992, IBM completed the spin-off of its various non-mainframe and non-midrange, personal computer manufacturing divisions, combining them into an autonomous wholly-owned subsidiary known as the IBM Personal Computer Company (IBM PC Co.). This corporate restructuring came after IBM reported a sharp drop in profit margins during the second quarter of fiscal year 1992; market analysts attributed the drop to a fierce price war in the personal computer market over the summer of 1992. The corporate restructuring was one of the largest and most expensive in history up to that point. By the summer of 1993, the IBM PC Co. had divided into multiple business units itself, including
Ambra Computer Corporation and the IBM Power Personal Systems Group, the former an attempt to design and market "
clone" computers of IBM's own architecture and the latter responsible for IBM's
PowerPC

workstations. IBM PC Co. introduced the
ThinkPad clone computers, which IBM would heavily market and would eventually become one of the best-selling series of
notebook computers.
In 1993, IBM posted an $8 billion loss – at the time the biggest in American corporate history.
Lou Gerstner was hired as CEO from
RJR Nabisco to turn the company around. In 1995, IBM purchased
Lotus Software, best known for its
Lotus 1-2-3 spreadsheet software. During the decade, IBM was working on a new operating system, named the
Workplace OS project. Despite a large amount of money spent on the project, it was cancelled in 1996.

In 1998, IBM merged the enterprise-oriented Personal Systems Group of the IBM PC Co. into IBM's own Global Services personal computer consulting and customer service division. The resulting merged business units then became known simply as IBM Personal Systems Group. A year later, IBM stopped selling their computers at retail outlets after their market share in this sector had fallen considerably behind competitors
Compaq and
Dell. Immediately afterwards, the IBM PC Co. was dissolved and merged into IBM Personal Systems Group.
In 2002 IBM acquired PwC Consulting, the consulting arm of

Continuing a trend started in the 1990s of downsizing its operations and divesting from
commodity production, IBM
sold all of its personal computer business to Chinese technology company
Lenovo and, in 2009, it acquired software company

unstructured data. Watson was debuted in 2011 on the American game show ''
Jeopardy!'', where it competed against champions
Ken Jennings and
Brad Rutter in a three-game tournament and won. Watson has since been applied to business, healthcare, developers, and universities. For example, IBM has partnered with
Memorial Sloan Kettering Cancer Center to assist with considering treatment options for
oncology patients and for doing
melanoma screenings. Several companies use Watson for call centers, either replacing or assisting customer service agents.
IBM also provides infrastructure for the
New York City Police Department through their
IBM Cognos Analytics to perform data visualizations of
CompStat crime data.
In June 2020, IBM announced that it was exiting the facial recognition business.

Brand and reputation

IBM is nicknamed ''Big Blue'' partly because of its blue logo and color scheme,
and also in reference to its former ''de facto''
dress code of white shirts with blue suits.
The company logo has undergone several changes over the years, with its current "8-bar" logo designed in 1972 by
graphic designer Paul Rand. It was a general replacement for a 13-bar logo, since period photocopiers did not render narrow (as opposed to tall) stripes well. Aside from the logo, IBM used
Helvetica as a corporate typeface for 50 years, until it was replaced in 2017 by the custom-designed
IBM Plex.
IBM has a valuable brand as a result of over 100 years of operations and marketing campaigns. Since 1996, IBM has been the exclusive technology partner for the
Masters Tournament, one of the four
major championships in professional golf, with IBM creating the first Masters.org (1996), the first course cam (1998), the first
iPhone app with live streaming (2009), and first-ever live 4K Ultra High Definition feed in the United States for a major sporting event (2016). As a result, IBM CEO
Ginni Rometty became the third female member of the Master's governing body, the
Augusta National Golf Club. IBM is also a major sponsor in professional tennis, with engagements at the
U.S. Open,
Wimbledon, the Australian Open, and the French Open. The company also sponsored the
Olympic Games

Environmental
In 2004, concerns were raised related to IBM's contribution in its early days to pollution in its original location in
Endicott, New York. IBM reported its total
CO2e emissions (direct and indirect) for the twelve months ending December 31, 2020 at 621 kilotons (-324 /-34.3% year-on-year).
[Alt URL]
In February 2021, IBM committed to achieve net zero greenhouse gas emissions by the year 2030.
Tax avoidance
In 2018, IBM along with 91 additional
''Fortune'' 500 companies had "paid an effective federal tax rate of 0% or less" as a result of Donald Trump´s
Tax Cuts and Jobs Act of 2017.

Workplace culture
Employees are often referred to as "IBMers". IBM's culture has evolved significantly over its century of operations. In its early days, a dark (or gray) suit, white shirt, and a "sincere" tie constituted the public uniform for IBM employees.
During IBM's management transformation in the 1990s, CEO
Louis V. Gerstner Jr. relaxed these codes, normalizing the dress and behavior of IBM employees.
The company's culture has also given to different plays on the company acronym (IBM), with some saying it stands for "I've Been Moved," based on frequent relocations,
others saying it stands for "I'm By Myself" pursuant to a prevalent work-from-anywhere norm, and others saying it stands for "I'm Being Mentored" in reference to the company's open door policy and encouragement for mentoring at all levels.
The company has traditionally resisted
labor union organizing, although unions represent some IBM workers outside the United States.
