This trend of refusing advertising for movies that the news divisions will likely cover is something our editorial (gratis!) focused on this week. I'll let the editorial speak for itself, but wanted to end with this salient comment from HuffPost (and echoed by us).
Oh, and one last thing - before NBC execs erect their statutes on the altar of advertising integrity, ETP couldn't help but notice that the network's new meta-sitcom, "30 Rock," contained a plot point in the pilot s pegged on an actual GE three-way convection oven - then followed up with a commercial for the oven during the second episode. Funny how a GE-owned network manages to plug GE goods and still tout its ethical approach to endorsement of commercial products.
