One of the first open source programs I'll feature has heritage from one of the programs that started the open source revolution.
Once upon a digital time, there was a web browser named Netscape Navigator. It was launched in the early 1990s. I do remember using it once or twice in an internet cafe. It set the standard for web browsing until Microsoft bundled Internet Explorer in Windows. Since Internet Explorer was built-in in Windows, people didn't need to buy Netscape Navigator anymore. So Microsoft basically shut down Netscape's business.
