Just in case you don't have enough to do, allow me to suggest the addictive new blog, PRDepiction, a group blog with citations from research on pop culture representations of public relations, as well as cites and/or links to the primary sources. (Disclosure: I'm one of the bloggers. Further disclosure: I haven't posted on the site yet. But I will.)
It's addictive because, c'mon, you can call it research!
