The oil boom of the late 19th/early 20th century led to the rapid growth of boomtowns as thousands of people moved to new oil fields. This dramatically increased the populations of places like Beaumont and Sour Lake. The automobile industry grew successful using gasoline from oil in internal combustion engines. Petrochemical industries also emerged producing rubber, plastics, and carbon black from oil. Texas passed laws regulating the oil industry and collecting taxes on oil to support education. The permanent university fund was established using land designated for education, supported by oil royalties and philanthropy which continues to benefit the University of Texas and Texas A&M systems.
