All I know is the following:

Linux exists on many devices in embedded form: things like routers, modems, GPS systems, etc. It will usually say when you buy the device that the sources for GPL v2 software is available at their website, this means Linux.

It is also used in some real-time systems, read:

I've split your thread-jacking post and two responses out
of the unrelated thread.

Linux is just the free version of unix. (someone correct me)

So whatever you learn from linux will definitely help you with a career in networking using unix or other derivatives.

Check out the *nix family tree.

and
http://en.wikipedia.org/wiki/Unix

Okay.
Linux is not derived from Unix source code, but its interfaces are intentionally like Unix.

Note that Linux is not connected to Unix in the diagram from your Wikipedia link.

Well, Disney uses(or used, I don't know) it for animation.
As far as I know, some people use it for render farms.
It can be used for various servers (HTTP/FTP/Mail, even game servers), in supercomputers, for distributed computing, and many other things.

AFAIK, FreeBSD is more like "free version of unix".

Linux is used by just about every industry.
Strictly speaking its a Unix look-alike. as its not actually derived from Unix (due partly to legal issues) and they've never applied for formal Unix certification.
However, for most practical purposes you can think of it as a free 'Unix'.
You can read through this site if you want the gory details. http://www.unix.org/what_is_unix/history_timeline.html

linux is used , like someone rightly said above in data centers to host websites - more than any other system, if that is correct.
who pays the developers - hmm, that is a good question I've often wondered myself - who would pay a programmer some money to write software that will be released for free to the public? but they do, for example Redhat. that's just the crazy way it works.
as for whether it'll be around in 20 years, well , I doubt anyone can predict that - but if it's history is anything to go by, it dedinitely should!

Before answering this question, you have to understand that linux is _ONLY_ a kernel, this is _NOT_ an operating system.

A kernel is "just" the program which deal with resources like peripherals, memory, process and so on...

To have a complete operating system you need a kernel a many programs like consoles, shell, windows manager, text editor, files and directories management programs... That's why purists say GNU/Linux when they're talking about the operating system: this linux kernel and GNU set of programs...

Now, some major companies like INTEL or IBM pay developers to develop drivers and or compiler which work fine on their architecture, this is a way to win more linux customers. Some others use open sources program (or libraries or system...), and if they find a bug, add fonctionnalities, or improve performance they have too release their modifications due to the GPL license. Another way to make business with open source product is to sell service and technical advice for an open source product (is it the way used by RedHat and many more). But don't forget that many developers like writing program, and they do that for their own pleasure, or because they don't find a program which fit their needs, and then they release the sources to have some feedback, or just because they are proud of their products.

yes, semantically linux is the open-sourced re-implementation of unix. the kernel was created without access to the unix source-code.

Well, I think Mac is actually considered *nix, as far as I know it is unix-based.

It uses a Unix/Linux style kernel, hence the 'X' in the name...
