A federal judge in Manhattan issued a 160-page ruling today finding that Apple colluded with five major U.S. publishers to increase retail prices of e-books ahead of the company’s entrance into the market in 2010, The Wall Street Journal reports."Understanding that no one Publisher could risk acting alone in an attempt to take pricing power away from Amazon, Apple created a mechanism and environment that enabled them to act together in a matter of weeks to eliminate all retail price competition for their e-books," U.S. District Judge Denise Cote wrote. A separate trial for damages will follow, and Apple has said it will appeal the ruling
