Hollywood is "Dream Factory"
By the 1920's Hollywood was the world's movie capital. During that time, Hollywood took pride in being the world's leader by recruiting Europe's most talented actors, actresses, directors, as well as camera operators, lighting technicians, and set designers. At the end of the decade, Hollywood was already the fifth largest industry, claiming 83 cents out of every dollar Americans spent on entertainment.
