Esso
American
Esso is the long-used trade name of ExxonMobil, originating with the growth of Imperial Oil, founded by sixteen refiners in London, Ontario, in 1880. Standard Oil of New Jersey acquired a controlling interest in Imperial Oil in 1898, integrating it into the wider Standard Oil network. The familiar Esso brand — derived phonetically from the initials "S-O" for Standard Oil — was formally applied for trademark protection in 1923, becoming one of the most recognizable names in North American petroleum marketing. - AsNotedIn
