* * *IBM: Brief Chronology * * *
IBM's history of growth and strength in the computer industry is legendary. The initials "IBM" are synonymous with computers and software.
From its early beginnings as the Computing-Tabulating-Recording Company, it grew from a modest 1,200 employees and three product lines, to over 400,000 employees and hundreds of products by the early 1980's. IBM's annual sales increased from $1.4 million in 1914 to $140 million by the end of World War II.
During the stock market crash of 1929, IBM struggled but managed to survive without laying off employees. IBM has remained a leader in the information-processing field throughout the world. Even though it entered the emerging personal computer market only after others were producing computers and gaining acceptance, IBM quickly used its size and resources to dominate the PC market for a number of years. IBM's influence in the personal computing field is extremely strong, but it is challenged by the rapid changes in technology and the growing trend of businesses away from large scale computers to greater reliance on microcomputer, LAN and client-server type solutions.
Growing international competition and the U.S. economic recession of the early 1990's, adversely affected IBM and many other computer companies. From 1990 to 1993, in efforts to streamline operations, cut costs and increase competitiveness, IBM was forced to lay off about 100,000 workers world-wide.
IBM has since grown into a multi-billion dollar company. IBM is the world leader in the production of large-scale computers, personal computers, computer peripherals, software, and the largest provider of computer services and maintenance. Only AT&T and Northern Telecom surpass IBM in the data communications field. By 1993, IBM ranked as the fourth largest corporation in the world with sales of $65 billion and assets of over $87.7 billion.
INTERNATIONAL BUSINESS MACHINES CORPORATION - Brief Chronology
DATES and EVENTS
On December 3, 1886,Herman Hollerith (1860-1929) organized the Tabulating Machine Company (TMC) with an initial capitalization of $100,000. Hollerith became general manager. In 1911, he sold his company to the Computing-Tabulating-Recording Company (CTR) for about $1 million.
On July 5, the Computing-Tabulating-Recording Company (CTR) is founded. The CTR was organized by Charles R. Flint from a group of smaller companies including the "Tabulating Machine Company" (founded by Herman Hollerith and sold in 1911), the "Dayton Scale Company" (Dayton, Ohio), the "International Time Recording Company" (Endicott, New York) and the Bundy Manufacturing Company (Endicott, New York). The Computing-Tabulating-Recording Company later changes its name to IBM.
Thomas J. Watson, Sr. joins CTR as general manager.

The Type 601 improved multiplying punch is introduced.
The Type 405 Tabulator is introduced. The 405 model was also called the Alphabetical Accounting Machine. The 405 had a removable control panel and could tabulate 150 cards per minute.
IBM, in cooperation with Columbia University, develops the International Test Scoring Machine (ITSM).
IBM gives its support to build a large scale automatic calculator (later called the ASCC) and enters into an agreement with Harvard University.
The IBM Automatic Sequence Controlled Calculator (ASCC) is presented to Harvard University on August 7, 1944. The ASCC was over 51 feet long and 8 feet high. It contained 3,300 relay components, 2,200 counter wheels and weighed over 5 tons. Work on the development of the ASCC was done by Howard Aiken, Clair D. Lake, Frank E. Hamilton, Benjamin M. Durfee and James W. Bryce. The machine, which was operational for over 15 years, was later known as the Harvard Mark I.
IBM produced the Pluggable Sequence Relay Calculator (PSRC) for the U.S. Army.

In January 1948, the IBM Selective Sequence Electronic Calculator was dedicated by T. J. Watson, Sr., at the IBM showroom, Madison Avenue, New York, New York. The SSEC was set up around the periphery of a 60 foot by 30 foot room. It contained over 20,000 relays and 12,500 vacuum tubes. IBM had also used the machine internally, through Wallace J. Eckert, director of IBM's Watson Scientific Computing Laboratory. The SSEC was IBM's largest and most powerful machine up to this time. The SSEC was used for a variety of problem solving applications, including problems in planetary orbits, atomic fields, fluids, optics, ordnance and hydrodynamics. In 1952, the SSEC was shut down and no longer used.
The IBM 604 Electronic Calculator is introduced. The 604 contained over 1,400 vacuum tubes. The 604 was designed with pluggable units, which improved the manufacturing, testing and repair processes. The model 604 was very successful and over 5,600 were made from 1948 until about 1958.

In January, IBM embarked on a program to develop a Defense Calculator, in response to U.S. military needs in light of the Korean Conflict. This research grows into the Type 701 computer.
By the end of 1951, IBM had completed its Tape Processing Machine
(TPM) which used magnetic tape and a large arithmetic logic unit (ALU) consisting of 2,500 vacuum tubes. The ALU assembly was referred to as the "main frame" which later became a common term for large computers. The maximum speed of the TPM was 70 inches per second, or about 7,000 characters per second. The TPM was demonstrated to government and military officials.
Work is done on the IBM Type 701 computer. The system included the analytical control unit, two electrostatic storage units, punched card reader, alphabetical printer, punched-card recorder, magnetic- tape recorder, two magnetic-tape reader and recorders, and a magnetic-drum reader and recorder. The 701 was promoted as being 25 times faster than the IBM SSEC of 1948.
IBM announces the Type 701, Electronic Data Processing Machine in April of this year. A total of 19 type 701 computers were built by IBM from April 1953 to April 1955. The last machine was purchased by the U.S. Weather Bureau for use by the Joint Numerical Weather Prediction Unit. The 701 was originally called the Defense Calculator.

Vincent Learson, Vice President of IBM's General Product Division and its Data Systems Division, viewed the System/360 as a major step in IBM's road to obtain a large share of the business computing market. The term "360" was chosen to emphasize the computer's versatile nature, covering a 360 degrees radius of business applications. Bob O. Evans, who was in charge of planning and development in IBM's Data Systems Division, chaired a committee to develop IBM's long range computer systems strategy. The committee made its recommendations in January 1962, which included the concept of the System/360. Over 1,000 computers are ordered within the first 30 days.

Did you know?
IBM got its nickname "Big Blue" not from the color of the computers but from the dark blue suits that its early sales force wore. IBM had one of the greatest sales forces in the country, even before IBM started making and selling digital computers.
