The idea of the digital age spawns not only from the change in technology, but from the affiliation that the word "digital" has with the idea of improvement in the future. But, what does all of this mean? From an audience's standpoint, mega business corporations are what run the film business, but in reality, the film business is being run by the audience.
Major film corporations, such as Ge, Disney, and Time Warner all run under the same idea: Create what will be consumed. With the switch from film cameras to cameras with a digital running, creating "good" movies has become much easier. This may bring you to ask, what, exactly, constitutes a movies as "good"? Since the change, it has become easier to try to perfect the shots during shoot days, and it has made the work day, in most cases, easier for not only the crew, but also the actors. Because of this, the structure of film technology has allowed for an easy transition within eras.
Moreover, the shift in "true power" from major corporations to the consumer has smoothened the passage between eras. In 1983, 90% of American media was owned by over 50 companies. In 2011, that same 90% was owned by 6 (packet). This change in power, in a way, simplified the diversity that was once provided by movies and created a cultural difference. These cultural differences were, by default, powered by the audience. If the common-people wanted to see a movie about and adorable pet becoming a mischievous monster, than by golly, the big-time corporations would make sure they would. This concept has stayed true to film throughout the years, and partnering with the major corporations and newfound technology, modern cinema has found itself in a brand new era: The Digital Age.
