NBC may want to rename its Thursday night lineup Might-See TV. For the first time on record, CBS beat NBC last Thursday among adults 18-49. Contributing to the Peacock network's woes: another disastrous performance from the hiatus-bound Coupling. (The moral of this story? Don't air TV shows that suck.) In other ratings news, Fox's coverage of the World Series averaged 20.1 million viewers over the six games — up from 19.3 million last year when no one cared who won.
