Esso Hat

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" from the phonetic pronunciation of Standard Oil's initials. Standard Oil of New Jersey started marketing its products under the Esso brand in 1926. In 1972, the name Esso was largely replaced in the U.S. by the Exxon brand after the Standard Oil of New Jersey bought Humble Oil, while the Esso name remained widely used elsewhere. In most of the world, the Esso brand and the Mobil brand are the primary brand names of ExxonMobil, while the Exxon brand is used only in the United States alongside Mobil.
