How do you best market your efforts

I have been in IT for 8 years and have seen many changes during that time. One thing that I would like input on is how I can best market my efforts internally.

Recently due to a lack of the business being aware of what IT really does they reduced head count. I want to learn from this and communicate what I have done and what I am working on in a way that doesn’t look like I am just trying to get attention.
