Peacock has had talks with the CW, Comcast Entertainment Networks (E!/G4) and TNT about sharing "Friday Night Lights" with NBC. DirecTV, which last year picked up the rights to NBC sudser "Passions," has also been brought into the mix.

Just how the shared window plan would work is unclear, but one model may be the plan NBC worked out for "Law & Order: Criminal Intent."

Starting this season, episodes of "CI" premiered on USA Network and aired a few months later on NBC. Skein has generated solid numbers in both windows.

Whether NBC U can work out a similar deal with a network it doesn't own remains to be seen. Already, some people familiar with the talks have complained that Peacock's asking price for "Friday Night Lights" is too high.
