Pick up any of the trade mags - Klixxx, XBizWorld, AVN Online, you'll find plenty of programs promoting themselves.... but as long as you keep an eye on the boards and the announcements and Press Releases, most programs (worth promoting) will take the proper steps to get their name out.
You can always find new programs just by following links from one page to the next too! I think we're all related in some way or another... six degrees of separation and all that.
