Founding Story
American Tower began in 1995 as a tower division inside American Radio Systems, the radio group Steven B. Dodge had built. His stations already owned tall broadcast towers, and the cellular carriers created by the mid-1990s spectrum auctions needed somewhere to hang antennas. Rather than have each carrier put up its own structure on the same hill, Dodge set up a neutral operator that would build once and lease to several competing carriers. When CBS acquired American Radio Systems in June 1998, the tower business was separated out as American Tower Corporation and listed on the New York Stock Exchange with more than 1,800 towers across 44 states and the District of Columbia.
Founders
Steven B. Dodge
Unlike legacy media or manufacturing companies, American Tower was not founded by a solitary inventor in a garage; it was a calculated, strategic spin-off orchestrated by a broadcasting conglomerate anticipating a structural shift in the telecommunications industry. The company was founded in 1995 as a subsidiary of American Radio Systems, a roll-up of local radio stations founded by Steve Dodge. In the mid-1990s, the United States was on the precipice of a cellular revolution. The federal government was auctioning off new spectrum, and dozens of new, heavily funded wireless carriers were rushing to build national networks. However, building out a network required physical infrastructure, specifically, thousands of tall steel towers to broadcast signals. Historically, telecommunications companies insisted on building and owning their own proprietary towers, viewing them as a competitive advantage. Steve Dodge, the CEO of American Radio Systems, recognized a financial inefficiency. His radio stations owned dozens of tall broadcast towers. He realized that rather than every new cellular company building their own redundant tower on the same hill, it would be infinitely more efficient for an independent, neutral third party to build one tower and lease space to multiple competing carriers. In 1995, he formally created American Tower Systems as a subsidiary to execute this exact vision. When CBS acquired American Radio Systems in 1998 for its radio assets, American Tower was spun off into an independent, publicly traded company. Under Dodge's leadership, the company acquired thousands of existing towers from carriers who needed cash, transforming the entire economic architecture of global telecommunications infrastructure. Steven B. Dodge was born in 1945 in New Haven. Education: Yale University.

Dodge handing the chief executive role to James Taiclet in October 2003.
