The “Studio Zone” is the technical term for what is sometimes referred to as the "Thirty Mile Zone" or "TMZ," which generally refers to the area within a 30-mile radius of the intersection of West Beverly Boulevard and North La Cienega Boulevard in Los Angeles, California. Under collective bargaining agreements covering entertainment industry union workers, different rules and working conditions apply inside and outside the zone. Today, there are actually two zones: the Studio Zone and a Secondary Studio Zone.
