Movies and their impact on society

My big question is, I am going to research how movies are such a big impact on society. During research, an article explained how society now not only watches movies for only enterteinment but also for for relaxation. After a hard day of work or a long day at school people usually go home and relax to a nice movie and maybe a few snacks. Basically after a stressfull day movies help clear our minds and allow us to get rid of their burden. But in the 19th century when movies had first come up as an idea, there wasn't exaclty an influence on society. When it was time to get a part for a movie it was discipline, sobriety and reliability. But now it is sexual appeal that get someone a job in the movie bussiness. I guess that the main idea of this speal is that movies are looked up upon and people want to be like them and the people that produce them are a great influence.
