Why did Rockefeller become intersted in the oil business?

John D. Rockefeller became interested in the oil business due to the growing demand for kerosene, which was used for lighting homes and businesses in the late 19th century. Recognizing the potential for profit, he co-founded Standard Oil in 1870, focusing on refining and distributing oil. His business acumen and innovative practices, such as vertical integration and efficient production methods, allowed him to dominate the industry and significantly influence the oil market.
