What's the difference between creative writing and professional writing?

I think the expression creative writing is mostly used to refer to literature but I consider all kinds of writing to be creative except for academic or technical writing which focus more on information rather than style. In my field for example, the text is used for brochures and marketing campaigns so it used professionally or through a profession. It has to be creative still! That's my own view of it :) You can do some search online to know whether the terms have specific definitions. Here's what wikipedia is saying: http://en.wikipedia.org/wiki/Professional_writing and http://en.wikipedia.org/wiki/Creative_writing
