The Esso name was primarily used by its predecessor, Standard Oil of New Jersey, after the breakup of the original Standard Oil company in 1911. The name Esso is the phonetic pronunciation of the initials 'S' and 'O' in the name Standard Oil. Standard Oil of New Jersey started marketing its products under the Esso brand in 1926. In most states, the company used the Enco (Energy Company) brand name, and in a few, the Humble Oil brand name. Esso Gas Stations were primarily found in the eastern United States and some states in the Midwest. By 1972, the name Esso was largely replaced in the U.S. by the Exxon brand after the Standard Oil of New Jersey bought Humble. The Esso name remained widely used elsewhere. In most of the world, the Esso and Mobil brands are the primary names of ExxonMobil, while the Exxon brand is used only in the United States alongside Mobil. The Esso brand name was discontinued in the U.S. by 1977, yet the brand name continues in Europe. Today, it is a trading name for ExxonMobil.
