David J. Markey, the president's chief adviser on telecommunications and information policy, will join the private sector in two weeks after a long career in government and politics.

Markey, 45, will leave his job as assistant secretary of Commerce and administrator of the National Telecommunications and Information Administration to become vice president for federal regulatory affairs for BellSouth Corp., one of the offspring from the breakup of AT&T.

In an interview, Markey said he was approached by other Bell operating companies, but accepted the offer from BellSouth primarily because he was impressed with the company's government relations staff and senior management. He said he has a great deal of respect for his soon-to-be boss, R. L. Mickey McGuire, BellSouth's senior vice president of governmental affairs and formerly a congressional representative for American Telephone & Telegraph Co.

In his new post, Markey, a strong opponent of government regulation of the communications industry, will manage the company's relations and argue its cases before the industry's principal regulator, the Federal Communications Commission. He also is a former special assistant to the FCC's chairman, Mark Fowler.

McGuire said Markey would bring to the company broad experience of the government processes that affect BellSouth. "He's also been quite active in international policy, and we hope to draw upon his experience as our company enters the world market," McGuire added.

However, Markey will be restricted somewhat in his new job by federal law, which, in certain cases, prohibits former government officials from working directly on issues that they were involved in while with the government. Markey said he thought the law would limit his dealings with Commerce and NTIA, where he was most recently, and with certain cases that he worked on closely, such as the administration's ruling allowing competitors to Intelsat, the global satellite communications network. But, he said, they would limit his work with the FCC less.

A native of Frederick and graduate of University of Maryland School of Law, Markey also has served as chief of staff and legislative director for Sens. Frank Murkowski (R-Alaska) and J. Glenn Beall (R-Md.), and was vice president of congressional relations for the National Association of Broadcasters. FINANCIAL SERVICES
