Take the following as truth: Hollywood first became the center of the film industry in the 1920s, after Cecil B. DeMille set up the town's first movie studio near Highland and Sunset in a horse barn and filmed The Squaw Man, the first feature-length film, in 1913.
Then the following statement: "After Cecil B. DeMille, many more people flocked to Hollywood to establish studios." is true, false, or inconclusive?
