COMPANY TOWN ANNEX

Talks between Metro-Goldwyn-Mayer and Cablevision on a possible alliance involving MGM’s library of more than 5,000 films have stumbled, sources said. New York-based Cablevision, which controls Radio City Entertainment and Madison Square Garden, had been among the three most active bidders for Livent in a process that stretched for months. Cablevision representatives had been scheduled to meet Thursday with MGM officials, but MGM’s new chief executive, Alex Yemenidjian, called off that meeting after Cablevision made a proposal whose financial size he decided “wasn’t appropriate,” one source said.
