Vivendi SA won a bidding war for Brazil’s GVT (Holding) SA late last week, which one analyst said is a “clear signal” the company is planning to sell its 20 percent stake in NBC Universal, in order to pay for the new acquisition, Bloomberg reports.

The window for Vivendi to sell its stake opened Sunday. A sale would pave the way for Comcast to take a controlling stake in NBC U.
