Verizon Communications Inc. (NYSE: VZ, NASDAQ: VZ), branded as Verizon (/vərˈaɪzən/), is an American broadband and telecommunications company and a component of the Dow Jones Industrial Average. It started in 1983 as Bell Atlantic (based in New York City) with a footprint covering New Jersey to Virginia and emerged as part of the 1984 AT&T breakup into seven "Baby Bells." In 1997, Bell Atlantic merged with another Regional Bell Operating Company, NYNEX, based in New York City with a footprint spanning from New York to Maine. The combined company kept the Bell Atlantic name. In 2000, Bell Atlantic acquired former independent phone company GTE, and adopted the name "Verizon", a portmanteau of veritas and horizon. The company's headquarters are located in the Verizon Building at 140 West Street in Lower Manhattan, New York City.
