Verizon Communications Inc. 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, consisting of the separate operating companies New Jersey Bell, Bell of Pennsylvania, Diamond State Telephone, and C&P Telephone, 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. Bell Atlantic was the surviving company name, and the merged company moved its headquarters from Philadelphia to NYNEX's old headquarters in New York City. In 2000, Bell Atlantic acquired GTE, which operated telecommunications companies across most of the rest of the country that was not already in Bell Atlantic's footprint. Bell Atlantic, the surviving entity, changed its name to Verizon, a portmanteau of veritas and horizon.
