In the early twentieth century, a group of scientists and mathematicians developed complex algorithms used to solve problems in mathematics and science.
In 1935, Alan Turing crafted the first theory of software. He published “On Computable Numbers” with Christopher Strachey, outlining his ideas on programming machines for mathematical calculations.
Tom Kilburn, a computer scientist from the University of Manchester in England, wrote the first computer software in 1948.

How was the first computer software invented?
Early computer programmers struggled with user-unfriendly systems. To operate a computer, you had to write code in a specific language. Producing and maintaining programs was also costly.
The first computer programs used raw machine code, which was hard to write and even tougher to change. In 1958, John McCarthy invented the Lisp programming language, simplifying software development. Lisp soon became the standard for programming.
Most software was still written in machine code despite Lisp’s popularity until the early 1960s. This started to shift with higher-level languages like Fortran and COBOL. These languages made it easier for people in engineering, scientific, and business environments to write software without a computer science background.
Deciding who invented computer software is tough. Some say John McCarthy deserves credit, while others believe the first software was in machine code. However, the development of higher-level languages in the early 1960s was a major turning point for the software industry.
What is the first software company in the world?
Computer Usage Company, founded in 1955, was the first to offer software products and services. It started small but quickly expanded due to rising software demand. The company’s first watershed project was an oil flow simulation for California Research Corporation.
Interestingly, Elmer C. Kubie, the founder of Computer Usage Company, was a mathematician and physicist, not a computer scientist. He recognized the potential of computers and ventured into the software industry. Kubie pioneered this field, and his company significantly contributed to the development of computer software.
What are the three types of software?
- System software is the basic set of programs that control the function of a computer. System software includes the operating system, which is the main program that organizes and controls how the computer’s hardware works. Other system software includes the BIOS, which is a program that starts up the computer and helps it run properly, and the device drivers, which control how different pieces of hardware work.
- Utility software helps you use your computer more efficiently. Utility programs include the word processor, the spreadsheet program, and the calendar program. They allow you to create documents, do math, and keep track of your schedule.
- Application software is the type of software that lets you do something specific with your computer. For example, there is software that enables you to edit photos, software that allows you to play games, and software that lets you listen to music. Application software is what most people think of when they hear the word “software.”
The impact of computer software on society
The development of computer software has greatly impacted the economy. Businesses now operate more efficiently, leading to job creation. People can do things that were once impossible, such as online banking, shopping, and even dating.
Computer software is transforming education, allowing students to learn in innovative ways and preparing them for future careers.
Computer software is a powerful tool for social change. It significantly impacts the economy, education, and daily life. It shapes society in unprecedented ways, paving the way for the future.
