Federal officials sought to lay the groundwork Thursday for a key argument in its historic antitrust case against AT&T and Time Warner, attempting to show how the $85 billion mega-merger could lead to sharp subscriber declines among AT&T's rivals in the TV business.

Cable companies and other TV providers could lose roughly 12 percent of their customer base in the event of a protracted, hypothetical programming dispute with an AT&T-owned Time Warner, said John Hauser, a marketing professor at the Massachusetts Institute of Technology, who appeared in federal court Thursday as the Justice Department's expert witness.
