Sony Pictures Television has assumed global distribution functions for syndicated TV game shows "Wheel of Fortune" and "Jeopardy!" citing failure by CBS Studios to live up to contract terms, the company said in a letter to CBS on Monday.

Doubt Ryan Seacrest and Vanna White will be saying the letters C-B-S this week on Wheel of Fortune, but the still Shari Redstone-owned company just lost a hold on one of its gameshow goldmines, at least according to Sony.

The fight between Sony and CBS over 'Wheel of Fortune' and 'Jeopardy' intenisifies as Sony aims to take over distribution of the shows by next week.
