For the past couple of decades, Apple computers have been over-represented in movies, TV shows, magazines photos and DJ booths. Sure, some of them were paid product placements,but I bet it was mostly free because the creatives (photogs, prop wranglers/set designers) genuinely liked Apple and/or had an Apple computer conveniently on hand. This was instrumental in making Apple 'cool'. That free advertising alone is worth billions (including home DVDs and reruns)
