Without the permission of their company, no one can make a movie or show a movie. Edison wanted to control every link of this industry in his own hands, so that he could make countless money, but this practice would make the film industry unable to develop and progress. So before long, other filmmakers protested his behavior and started to set up their own companies to produce and broadcast their own films.
Edison used two methods to deal with this kind of thing. At first, he used the law to defend his rights. Later, he set up a commercial spy agency. I've been spying on other companies and letting hooligans go to other companies to sabotage them. Those companies also fight back desperately, so they often fight for all kinds of things, and what's more serious is armed conflict. From this point of view, although Edison made great contributions to the film industry, his various practices also limited the development of the film industry.
So many people in the film industry went abroad to develop, and those who didn't go abroad also went to California, which is far away from him. Because of the distance, he can't hire thugs to sabotage, and the local judicial department doesn't like him. Even if he goes to court, he won't seriously implement it. So slowly all kinds of filmmakers went to California to develop. At the beginning of the 20th century, an American director went to California to find a suitable place for filming. They walked all the way from Los Angeles to a small town on the outskirts of Los Angeles. After various considerations, the director decided to make movies here, and other industries also came here to make movies, so this town became Hollywood.
