Verizon Communications Inc., commonly known as Verizon, is an American multinational telecommunications conglomerate and a corporate component of the Dow Jones Industrial Average. The company is headquartered at 1095 Avenue of the Americas in Midtown Manhattan, New York City, but is incorporated in Delaware. In 1984, the United States Department of Justice mandated AT&T Corporation to break up the Bell System into seven companies, each a Regional Bell Operating Company, commonly referred to as "Baby Bells". Bell Atlantic, one of the Baby Bells, came into existence the same year. Headquartered in Philadelphia, it became the parent of New Jersey Bell, Bell of Pennsylvania, Diamond State Telephone, and the C&P Telephone companies, with a trading area from New Jersey to Virginia. As part of a rebranding of the Baby Bells in the mid-1990s, all of Bell Atlantic's operating companies assumed the holding company's name. In 1997, Bell Atlantic expanded into New York and the New England states by merging with fellow Baby Bell NYNEX. While Bell Atlantic was the surviving company, the merged company moved its headquarters from Philadelphia to NYNEX's old headquarters in New York City. Wikipedia
