Apparently the reason for the TV spots being aired is that the settlement between Fox and WB is almost done, same reason Fox's Tom Rothman and WB´s Alan Horn were seen smiling at each other and back patting on the Golden Globes.
Court documents show that WB is pursuing Gordon for all damages WB might suffer from Fox's claims. Guess Gordon will be the only one to lose out of this mess.
