No single company manufactures Linux. The Linux kernel is developed by thousands of individuals and hundreds of companies around the globe. Many companies then release Linux with their own selection of programs, in what are called "distros."
The Linux what......?
The Linux kernel is what is called free open source and is not manufactured by any one particular company. If you are asking as to what computers can use Linux then the answer is that pretty much any PC can use a Linux based operating system. I am actually currently running my computer with Windows XP as well as Ubuntu 10.10 which is a Linux based operating system. Go to Ubuntu.com for more information and you can even download your own free Ubuntu 10.10 Live CD from which you can boot your computer to try Ubuntu without installing it on your hard disk, or if you like it enough you can actually also use it to install it on to your computer and you can even keep your current operating system and have what is called a dual-boot which is what I have. There are also lots of other Linux distros (distributions), like Fedora 14, Linux Mint 10, openSUSE and the list goes on and on, best of all, they are for the most part free!
No one company or group develops Linux - it's a group project. Linus Torvalds is the founder of the project, but he himself does little coding for the kernel these days, preferring to stay on the code-review side of the project.
