Ignoring for the moment that streaming is the future of movie rentals, I recently came across a DVD in a movie rental outlet that had a QR code that was a link to the trailer for the movie. I don't think I'd have watched the trailer if it meant typing in a URL. On the other hand, having watched the trailer, I didn't rent the movie!
