At the end of the 19th century, inventor Herman Hollerith created the tabulator. This machine serves the same purpose of adding, but has widespread practical applications. In the US, it was actively used for the census. Dr. Hollerith, yes, he earned his doctorate in tabulating machines, and he created an efficient accounting system that ran on electromechanical machines using punch cards.

IBM PC
Nobody believed in the personal computer. After all, until the mid-1980s, most people thought of a computer as a huge piece of hardware, taking up a room, requiring constant maintenance, and solving massive, complex problems. How could it possibly fit on a desktop in an office or at home? No way! And certainly only a madman could imagine a multi-billion-dollar market!
It turned out that the personal computer really did exist. In offices around the world, first on the desks of executives, and by the late 1980s, even on ordinary employees, the IBM PC was firmly established. The strength of the IBM brand lay in its impeccable quality and the very best technology... IBM's strength lay in its worldwide sales network and massive advertising budgets. All competitors were forced to give way; a monster entered the new market. Apple had a particularly tough time.
In 1964, the IBM System/360 mainframe entered the market. It revolutionized the market and set the course for mainframe development for 50 years. This mainframe was copied by several other countries that couldn't buy it directly. The USSR couldn't buy modern computers because it was under embargo. Other countries cloned for economic reasons. This is understandable, as copying is cheaper. IBM spent about $5 billion developing the Series 360, half the cost of building the atomic bomb. Another estimate puts IBM's costs at 5,000 years of man-hours.
At some point, IBM was faced with the challenge of printing on paper. At the time, the typewriter market was full of competitors, so IBM wisely acquired Electromatic. In the 1940s, typewriters became electromechanical, and by the 1978s, electronic.

Steve Jobs and Bill Gates both saw themselves as antithetical to IBM's culture (discipline, black suits, starched shirts and ties), so they wore jeans and wrinkled T-shirts. IBM's business processes were highly refined. It was a model corporation. Some say IBM practically founded the American business school. That's a topic for another series.

IBM's competitors included Compaq, Dell (formerly PC's Limited), Tandy, and Hewlett-Packard.

Smaller competitors included Olivetti, WYSE, Apple, Osborne, Xerox, Epson, Toshiba, Asus, and Acer.
