How IBM Started
Imagine a time when giant piles of paper records were the only way to track people, money, and goods. Governments and large companies needed a better way to handle all those numbers. That is where the story of IBM really begins, long before the famous name appeared.
In the late 1800s, a group of small firms built machines that could record time, weigh goods, and read punched cards. One of the most important was Herman Hollerith’s company, which used punched cards to help the U.S. Census process data faster than ever before. These early machines set the stage for modern information technology.
In 1911, a financier named Charles Flint brought several of these firms together. He formed Computing-Tabulating-Recording Company, or CTR, based in Endicott, New York. The new company sold punched-card tabulators, time clocks, and scales, and it quickly started to grow.
From CTR to IBM
CTR changed from a loose group of small firms into a focused business under Thomas J. Watson Sr. He joined the company in 1914 as general manager and became president on Monday, March 15, 1915. Watson pushed for discipline, strong sales methods, and a deep focus on customer service.
He also believed in training and company pride. Salespeople wore suits, went through extensive training, and attended big company meetings. These habits created a strong culture that set CTR apart from many other businesses of its time.
In 1924, CTR took on a new name: International Business Machines, or IBM. The new name reflected the company’s global goals and its focus on machines that helped businesses handle information. It also gave IBM a brand that would become known around the world.
Early Ups and Downs
The early decades were not always easy. The Great Depression in the 1930s reduced spending and made life hard for many firms. But IBM had long-term leasing contracts and key government work, which helped it continue to invest and grow.
IBM started to expand into other countries in Europe and Latin America. It adapted its machines to the needs of local governments and large organizations. This early global reach later became one of IBM’s strengths.
During World War II, IBM equipment helped with logistics, statistics, and wartime planning. The company also took part in projects like the Harvard Mark I, one of the earliest electromechanical computing machines. These efforts pushed IBM deeper into the world of advanced calculation.
From Punched Cards to Mainframes
After the war, the world was changing fast. Businesses and governments needed more powerful machines to handle growing volumes of data. IBM began to move from electro-mechanical gear to fully electronic computers.
In the 1950s, IBM launched early mainframes such as the 700 series and later the transistor-based 7000 series. These systems were large, expensive, and extremely powerful for their time. They became the backbone of data processing in finance, government, and industry.
The real turning point came in 1964 with the introduction of the System/360 family. For the first time, IBM offered a full line of compatible computers built around a common design. Customers could start with a smaller system and grow into larger models without rewriting all their software.
- System/360 became a major standard for business computing.
- It showed that a single design could serve many different client needs.
- It also required a huge investment that IBM viewed as a “bet the company” decision.
The PC Era and New Challenges
By the late 1970s and early 1980s, a new trend appeared: the personal computer. Small machines were moving into homes, schools, and offices. For a company known for big mainframes, this was a major change.
In 1981, IBM launched the IBM 5150 Personal Computer. It used an “open” design that relied on parts and software from other firms, including a new operating system from Microsoft. The PC became very popular and helped define what a personal computer looked like.
But the same open design also made it easy for other firms to build “IBM compatible” systems. These competing machines were often cheaper and spread very quickly. Over time, this intense competition reduced IBM’s share of the PC market and cut into profits.
- IBM had huge success with PCs but faced strong rivals using similar designs.
- The company remained strong in mainframes, but new trends in computing kept emerging.
- By the late 1980s and early 1990s, IBM faced falling profits and growing pressure to change.
Services, Software, and the Big Turnaround
By the early 1990s, IBM was in serious trouble. Costs were high, markets were shifting, and some experts thought the company might need to split into smaller parts. Many long-time strategies were no longer working well.
In 1993, Lou Gerstner became CEO. He came from outside the tech industry and brought a fresh view. Instead of breaking IBM into pieces, he kept the company together and focused on its strengths.
Gerstner shifted IBM’s focus from selling hardware to providing complete solutions. The company leaned into services, consulting, and software. Instead of just selling machines, IBM helped clients design and run entire systems.
- IBM Global Services became a major part of the business.
- Software tools for databases, middleware, and system management grew in importance.
- Cost cuts and cultural changes helped IBM become leaner and more client-focused.
Cloud, AI, and the New IBM
In the 2000s and 2010s, IBM continued to change. It sold its PC business to Lenovo in 2005 and later sold some server lines. These moves allowed IBM to focus more on higher-value areas like software, services, and advanced systems.
IBM also invested heavily in analytics, security, and cloud computing. The company explored artificial intelligence through its Watson projects. A key moment came in 2011, when Watson won the game show “Jeopardy!” against top human champions.
In 2019, IBM acquired Red Hat, a leader in open-source software and Linux-based platforms, in a large deal. This move aimed to make IBM a top player in hybrid cloud, where clients use a mix of private and public clouds. Later, IBM spun off its managed infrastructure business as Kyndryl in 2021, sharpening its focus on software, cloud, and consulting.
- IBM’s core now centers on hybrid cloud and artificial intelligence.
- Research in quantum computing adds a long-term area of growth.
- New acquisitions continue to strengthen IBM’s cloud and data tools.
