As a result of post-war (WWII) era suburban development, property values and taxes on land increased, even as fewer large parcels were available to the studios. Los Angeles development was widespread, resulting in urban sprawl. Most of the historic movie ranches have been sold and subdivided. A few have been preserved as open space in regional parks, and are sometimes still used for filming. In addition, studios have developed movie ranches in other regions, such as New Mexico, Arizona, and Texas.
