Open source is a special way to make computer software.

Most software is proprietary, which means the creators keep the instructions secret. In open source, the source code is free for anyone to see. Source code is the set of instructions that tells a program how to work. People can look at the code and make changes to it. They can even share their new version, called a fork, back to the community. This way of working is called a decentralized model. It encourages people to work together through open collaboration.

This way of working relies on something called peer production.

This happens when many people work together to create a single product. They share things like blueprints, code, and written documents with the public. This helps people everywhere have universal access to new tools. It also allows for universal redistribution of those designs. Because the instructions are open, anyone can fix a bug or add a new feature. This makes the software better for everyone over time.

Sharing technical information is an old idea that started long ago.

In the early days of cars, companies fought over patents. A man named George B. Selden held a patent for a gasoline engine. This allowed a small group to control the whole industry. However, Henry Ford won a legal challenge against that patent in 1911. After that, car makers began sharing their patents for free. By World War II, Ford and other companies shared hundreds of patents. This helped the whole industry grow without expensive lawsuits.

Modern open source software became a popular term in 1998.

A group of people wanted a new name for "free software." They felt the old name was confusing for businesses. They wanted to show that open source was good for commerce too. Christine Peterson suggested the name "open source" at a meeting in Palo Alto, California. Other leaders like Eric S. Raymond helped make the term famous. The term grew quickly as the Internet became more common. Now, large groups like the Apache Software Foundation support many projects.

Open source projects can be worth a huge amount of money.

For example, the Linux project has a market value of $16 billion. Other important projects include Git, which is worth $2 billion. MySQL is another big project valued at $1.87 billion. This model is used for many things beyond just computers. It is used in drug discovery and even for making hardware. People can use 3D printers to make open hardware designs for the cost of materials. This shows how sharing ideas creates great value for the world.
