Prior to about 1915, Nickelodeons were not specifically jewish. Until a Hungarian jew came along and opened the first Nickelodeon in Brooklyn in 1904 or so.
That jew was Vilmos Fried, AKA William FOX. The money from the Nickelodeons+loans was used to start Fox Film Corp. which would later become 20th Century Fox. Vilmos Fried was jewed out of his own company though. They tried to kill him, put him in prison, and destroyed all his old films.
Prior to the 1920's most film studios were based in New York and New Jersey, but they all started moving to Hollywood in the 19-teens and 1920's to escape patent and decency laws.
