Well, i remember the first time i heard a movie in Dolby Digital outside a Cinema i was shocked. The same thing happened to my friends, parents and my friend's parents. We were used to watch blockbuster movies in a crappy VHS picture and sound connected to the home stereo in the best case. And then just happened, really fast, almost from one day to another: the gods gave us the DVD and then the home theater. This thing spreaded like an epidemic desease and now, almost everyone i know, has a home theater system.
