Why advertise? Well, ShareTheTruth isn't going to go away long after the movie leaves theaters (which will still be a while too). There's the DVD, there's local screenings, there's the 1000 trainees to tour the country (and world?) giving Al Gore's slideshow, and then of course there's the whole global warming issue that will only intensify as time goes on.
