The first wide spread distribution of UNIX was the sixth version Edition V, but it has since been named System V ('System Five').
Linux ('linn-ux') was initally named Freax (which was a conjuntion of Free, Freak and X), as Linus Torvalds thought that people might think that he was big-headed in naming his operating system after himself. Luckily the person resonsible for distributing the code used the Linux name.
There are now between 7 and 10 million users of Linux, and more than 10,000 programmers. In fact, for real-time, multi-tasking embedded systems it is often the natural choice, as it has a proper kernal, which can be easily modified for specific tasks.
