On Nov. 22, New York-based hedge fund Alden Global Capital continued its drive to own as much of the American newspaper industry as it can with a bid to acquire Davenport-based Lee Enterprises, a publicly traded chain of 75 daily newspapers and several hundred other outlets. On Nov. 29, Lee adopted a “poison-pill” plan to protect itself from a hostile takeover while the company’s board considered the unsolicited offer from Alden. The shareholder rights plan would take effect if Alden gets control of more than 10% of Lee’s stock anytime in the next year. Lee's directors unanimously rejected Alden's offer on Dec. 9.
