IBM on June 15, 1911 in Binghamton a few miles west of as a "record company calculations tab" (CTR) company registration. In 1924, the calculation of tabulation record company (CTR) changed its name to International Business Machines Corporation (International Business Machines). In the hustle and bustle of the twentieth century, 20 years, IBM gradually found the company's direction, grasp the first major world development trends and opportunities - electrical automation era.

IBM Certification in 1932 $ 1,000,000 invested heavily in building the first corporate laboratories, the laboratory research and development throughout the 30's to IBM in technology products to obtain the lead. During the Great Depression in the whole, IBM has been investing R & D and new products, and its products than all the other companies are better, faster, more reliable, and it therefore has won the exclusive contract to the New Deal accounting project. IBM 1935 card statistical machine products have occupied the U.S. market 85.7%, IBM card machine companies have accumulated a large number of strong sales and strong sales of financial and service capabilities for the future to become the master of the computer field has laid an important foundation.

In the subsequent almost half a century, until the 80s of last century, IBM IBM Information Management Certification leading data processing industry. From the drilling machine to a computer, IBM has been leading the global computing power of technology, and continue to promote open society as a whole new world of computing. The number of epoch-making breakthrough technology and representation of events as a symbol, IBM into a technology pioneer in promoting the progress of the world

In 1944, IBM began their cooperation with Harvard University, has made the electron tube computer MARK-1 and MARK-2, then mix into the tube relay large computer SSEC.

Since the advent of the transistor computer, IBM developed a small data processing computer IBM1401, using a transistor circuit, magnetic core memory, printed circuit these advanced technologies, making the host volume greatly reduced, electronic data processing computer analysis of completely replacing the card machine. 000-M77 is used to develop the knowledge of electronic data processing computer. Subsequently, IBM in just five years of introduction of the four different types of computers, a total of more than 14,000 units sold, but also laid the IBM's leading position in the computer industry.

With the emergence of semiconductor integrated circuits, IBM actively involved in the production of the third generation of integrated circuit computer. In 1964, IBM 000-R18 launched a landmark System/360 mainframe computer, which declared the mainframe era. System/360 represents the advent of the computer world with a common language, they all share the code for the OS/360 operating system (rather than customized for each product with the OS). Since then, almost all of the computer world, research and development are the IBM360 series system as the base, becoming an important trend in the world. IBM360 marked the real birth of the modern computer.
