WASHINGTON (MarketWatch) -- The U.S. government threatened to fine Yahoo Inc. YHOO, +1.41% $250,000 a day in 2008 if the company didn't comply with a demand to hand over user data, the Washington Post reported. The Post's report has details from documents unsealed Thursday that show an ultimately unsuccessful legal battle by Yahoo to resist the government's demands. The documents show how federal officials forced U.S. tech companies to participate in the National Security Agency's PRISM surveillance program, the Post said.
