The 1970s and 1980s saw significant changes in the entertainment industry. The rise of blockbuster films like Jaws (1975), Star Wars (1977), and E.T. the Extra-Terrestrial (1982) transformed the way studios approached movie production. These films' massive success spawned a new era of big-budget productions, which in turn led to the establishment of new studios like Lucasfilm and Amblin Entertainment.
