What was the most important ingredient that allowed Los Angeles to grow so

large so quickly?

Hollywood made the city world-famous, and World War II brought new industry, especially high-tech aircraft construction. Politically the city was moderately conservative, with a weak labor union sector. Los Angeles had a strong economic base in farming, oil, tourism, real estate and movies. It grew rapidly with many suburban areas inside and outside the city limits.

Since the 1960s, growth has slowed-and traffic delays have become famous. Los Angeles was a pioneer in freeway development as the public transit system deteriorated. New arrivals, especially from Mexico and Asia, have transformed the demographic base since the 1960s. Old industries have declined, including farming, oil, military and aircraft, but tourism, entertainment and high tech remain strong.
