Infographics are generally created to relay statistical information in a graphical and easy to digest format. Not sure I see a way of creating an infographic to explain a subject.
Perhaps you could gather some stats on the industry and express those with some cool graphics. There are plenty of tools around the web to help you create the graphic, I've always found this post quite useful http://www.makeuseof.com/tag/awesome-free-tools-infographics/
Best of luck and be sure to post a link here when you have finished it.
