The big announcement is finally made. Under terms of the deal, the cable giant will pay $6.5 billion in cash and contribute programming valued at $7.25 billion for a 51 percent stake in NBC Universal. Also, the new NBC Universal entity will borrow $9.1 billion to give to GE, which retains a 49 percent stake. Jeff Zucker will be running the place and report to Comcast CEO Brian Roberts. It'll take many months, of course, before the deal passes regulatory scrutiny. Here's the Comcast release.
