The DVD that I obtained for Module 4 was Next. I rented from the video store. The current competition between DVDs and video on demand are Red Queens. The reason is that they did not hit the market at the same time. DVDs and video on demand are competing against one another and working to achieve the same goal (Thornburg, 2009). People spend money going to video stores to rent DVD movies, record them on a DVR, and video on demand they can rent the movie and watch it on their computer with some free of charge and some a fee.
I believe that DVDs and video on demand of McLuhan’s tetrad is reversal; it is setting the stage for its own replacement.
