Pulkit and me decided to lie our main focus on the development of technology in movies. Thus, we will essentially consider visual affects due to the fact that those are the reason why many people watch movies and they furthermore make movies more enthralling and interesting.
As we all know, visual affects have greatly developed over time. Just some few years ago, Star Wars embodied the first big milestone of the importance of technology in movies. Today's movies such as "300" or "The Expandables" prove how incredibly much technology movie makers have available today. For example there was literally no fights at all in "300" that were not animated.
