Esso is a trading name for ExxonMobil. Originally, the name was primarily used by its predecessor Standard Oil of New Jersey after the breakup of the original Standard Oil company in 1911. The company adopted the name "Esso", to which the other Standard Oil companies would later object.

ExxonMobil Corporation is an American multinational oil and gas corporation and the largest direct descendant of John D. Rockefeller's Standard Oil. The company, which took its present name in 1999 per the merger of Exxon and Mobil, is vertically integrated across the entire oil and gas industry, and within it is also a chemicals division which produces plastic, synthetic rubber, and other chemical products. ExxonMobil is headquartered near the Houston suburb of Spring, Texas, though officially incorporated in the U.S. state of New Jersey. It is the largest United States-based oil and gas producing company. ExxonMobil is also the eighth largest company in the world by revenue and the third largest in the US.
