Cable: Sony Pictures Entertainment, which has been trying for nearly two years to launch a game show channel on cable TV, is moving ahead without one of its partners. Mark Goodson Productions, which owned a minority stake, has pulled out. The reasons for MGP’s withdrawal are unclear, but one source said the family of the late Mark Goodson is divided about what it wants to do with the company. MGP is a longtime game show producer and is behind such programs as “The Price Is Right” and “Family Feud.” The pullout is not expected to hinder Sony’s plans to launch its game show channel--recently renamed The Game Show Network--by Dec. 1. Sony still has access to MGP’s game show library. The cable TV channel will initially feature old game shows with new “wrap-arounds,” and Sony executives hope it will eventually have an interactive element.
