Headings Ads

I am trying to figure out how to place different artwork at the top of the body area, and different ads, depending on taxonomy terms.

For instance for editorials I want to show a certain graphic, for sports a different one.

I can distinguish these because I set up Taxonomy Terms of 'Editorials' and 'Sports'.

In addition, when a user selects Sports, for instance, I want to show different ads in the sidebar.

I suspect there are modules that take care of this, but what are they?

thanks, Jim Hoyt.
