Herman Hollerith founded the Tabulating Machine Company in 1896, which was later incorporated in 1905, and later still became part of C-T-R. Hollerith received the first patents for his Electric Tabulating Machine in 1889.In 1911, Charles F. Flint, a trust organizer, oversaw the merger of Herman Hollerith&#39;s Tabulating Machine Company with two others: the Computing Scale Company of America and the International Time Recording Company. The three companies merged into one company called the Computing-Tabulating-Recording Company or C-T-R. C-T-R sold many different products including cheese slicers, however, they soon concentrated on manufacturing and marketing accounting machines, such as: time recorders, dial recorders, tabulators, and automatic scales.In 1914, a former executive at the National Cash Register Company, Thomas J. Watson, Senior becomes the general manager of C-T-R. According to IBM&#39;s historians, &#34;Watson implemented a series of effective business tactics. He preached a positive outlook, and his favorite slogan, &#34;THINK,&#34; became a mantra for C-T-R&#39;s employees. Within 11 months of joining C-T-R, Watson became its president. The company focused on providing large-scale, custom-built tabulating solutions for businesses, leaving the market for small office products to others. During Watson&#39;s first four years, revenues more than doubled to $9 million. He also expanded the company&#39;s operations to Europe, South America, Asia and Australia.&#34;In 1924, the Computing-Tabulating-Recording Company is renamed the International Business Machines Corporation or IBM.The U.S. Social Security Act was passed in 1935 and IBM&#39;s punched card equipment was used by the U.S. government to create and maintain employment records for the then current population of 26 million Americans.<p>IBM invents the Vacuum Tube Multiplier in 1943, which used vacuum tubes for performing calculations electronically.</p><p>In 1944, IBM and Harvard University jointly developed and built a Automatic Sequence Controlled Calculator or ASCC , also known as the Mark I. This was IBM&#39;s first attempt to build a computer.</p><p>IBM founded the Watson Scientific Computing Laboratory at Columbia University in New York.</p>In 1952, the IBM 701 was built, IBM&#39;s first solo computer project and its first production computer. The 701 uses IBM&#39;s magnetic tape drive vacuum technology, a precursor to magnetic storage medium.In 1953, the IBM 650 Magnetic Drum Calculator electronic computer and the IBM 702 were built. The IBM 650 becomes a best seller.In 1954, the IBM 704 was built, the 704 computer was the first to have indexing, floating point arithmetic, and an improved reliable magnetic core memory.In 1955, IBM stopped using vacuum tube technology in their computers and built the 608 transistor calculator, a solid state computer with no tubes.In 1956, the RAMAC 305 and RAMAC 650 machines were built. RAMAC stood for Random Access Method of Accounting and Control machines. RAMAC machines used magnetic hard disks for data storage.In 1959, the IBM 1401 data processing system was introduced, the first computer ever to achieve sales of over 10,000 units. Also in 1959, the IBM 1403 printer was built.In 1964, the IBM System 360 family of computers were. System 360 was the world&#39;s first family of computers with compatible software and hardware. IBM described it as &#34;a bold departure from the monolithic, one-size-fits-all mainframe,&#34; and Fortune magazine called it &#34;IBM&#39;s $5 billion gamble.&#34;<p>In 1944, IBM researcher Robert H. Dennard invented DRAM memory. Robert Dennard&#39;s invention of one-transistor dynamic RAM called DRAM was a core development in the launch of today&#39;s computer industry, setting the stage for development of increasingly dense and cost-effective memory for computers.</p>The 1970 IBM System 370, was the first computer to use virtual memory for the first time.IBM invented its first operational application of speech recognition that &#34;enables customer engineers servicing equipment to &#34;talk&#34; to and receive &#34;spoken&#34; answers from a computer that can recognize about 5,000 words.&#34; IBM also develops an experimental terminal that prints computer responses in Braille for the blind.In 1974, IBM invents a networking protocol called Systems Network Architecture (SNA). .IBM invents the experimental 801. The 901 ia a Reduced Instruction Set Computer or RISC architecture invented by IBM researcher John Cocke. RISC technology greatly boosts computer speed by using simplified machine instructions for frequently used functions.In 1981, the IBM PC iwas built, one of the first computers intended for home consumer use. The IBM PC costs $1,565, and was the smallest and cheapest computer built to-date. IBM hired Microsoft to write an operating system for its PC, which was called MS-DOS.IBM researchers invented scanning tunneling microscopy, that produces for the first time three-dimensional images of the atomic surfaces of silicon, gold, nickel and other solids.IBM Zurich Research Laboratory fellows Gerd K. Binnig and Heinrich Rohrer win the 1986 Nobel Prize in physics for their work in scanning tunneling microscopy. Drs. Binnig and Rohrer are recognized for developing a powerful microscopy technique which permits scientists to make images of surfaces so detailed that individual atoms may be seen.IBM&#39;s Zurich Research Laboratory fellows J. Georg Bednorz and K. Alex Mueller receive the 1987 Nobel Prize for physics for their breakthrough discovery of high-temperature superconductivity in a new class of materials. This is the second consecutive year the Nobel Prize for physics has been presented to IBM researchers.IBM scientists discover how to move and position individual atoms on a metal surface, using a scanning tunneling microscope. The technique is demonstrated at IBM&#39;s Almaden Research Center in San Jose, California, where scientists created the world&#39;s first structure: the letters &#34;I-B-M&#34; - assembled one atom at a time.
