Linux naming controversy

In 1984, The Free Software Foundation, founded by Dr. Richard Stallman, made an attempt to create a free Unix-like operating system, which they called the GNU system.

They began with the necessary tools for the system, such as a compiler, debugger, and a text editor. Their plan was to then create a kernel to place beneath the tools that they had created. Unfortunately, the foundation was very late in producing a stable release, and even to this day development of the HURD (the GNU kernel) continues without a stable first release.

It was during this time that Torvalds first introduced his kernel. Before Linux, hackers had no choice but to use non-free kernels, most notably Minix. While the GNU kernel began to look more and more like vaporware every day, the community received Linux with open arms and many began to contribute.

From gnu.org: "Variants of the GNU operating system, which use the kernel called Linux, are now widely used; though these systems are often referred to as “Linux”, they are more accurately called GNU/Linux systems."

The GNU Project members decided to call 'Linux' GNU/Linux, in order to attribute credit to those who worked hard at creating the tools that the Linux kernel runs. Torvalds, however, has made no effort to hide his thoughts towards this naming convention, saying that "calling Linux in general just 'GNU/Linux' I think is ridiculous."
