When G.E. snatched up 20 percent of NBC Universal from Vivendi for $5.8 billion in preparation for its deal with Comcast, it looked like NBCU's value would come in at $29 billion. But tomorrow when the terms of the deal that will give Comcast a 51 percent stake in NBCU are announced, it will be valued at a much greater $37.25 billion. The biggest reason for the jump is the $7.25 billion value assigned to Comcast's cable channels (E!, Golf Channel, etc.), which will become part of the new company. Now that this is done, regulatory approval could take up to a year. Which means time is running out to stock up on Sheinhardt Wig Company t-shirts.
