“Wheel of Fortune” and “Jeopardy!” are two of TV’s best known programs, and have been churning out profits for years. Sony Pictures Television—which makes “Wheel of Fortune” and “Jeopardy!”—is suing CBS the distributor, for allegedly undercutting the value of the shows to serve its own interests. CBS licenses the shows to television stations and sells some ad space in them, receiving a cut of the revenue.
