Comcast, the largest cable network in the US, is reportedly in discussions with General Electric (GE) over a stake in NBC Universal, owner of the NBC television network. Analysts have valued NBC Universal (NBCU) at between $21 billion and $35 billion, including an estimated $5.1 billion in debt. The stake under discussion is around 50 percent, though the deal would partly depend on French media conglomerate Vivendi relinquishing its 20 percent holding.
