Blockbuster is in talks with cell-phone manufacturers to adapt their products so that they can receive full-length movies via Blockbuster's Movielink service. Speaking to the Reuters Media Summit in New York Wednesday, Blockbuster CEO Jim Keyes said that in order to keep up with current movie fare he often downloads movies from Movielink onto a memory card that he then plugs into his Blackberry. But that allows him to watch only in "bite-sized pieces," he said. The challenge is how do I make this convenient for everybody?"
