Blockbuster, attempting to fend off determined competition from online rental outfits and kiosk operators, said Monday that it will begin renting many older movies for as little as 99 cents beginning in January. "The 99-cents plan is targeted at the value-conscious consumer in this challenging economy," chairman and CEO Jim Keyes said at the Reuters Media Summit in New York. According to Video Business magazine, the company has also begun evaluating proprietary kiosks of its own in test locations.
