SERIES PREMIERE: So, so much of CBS’s fortunes, literally and figuratively, are riding on the success of this brand-new Thursday night football franchise. CBS, until January, even is shifting its top-rated Big Bang Theory back to Mondays to make room – room for a new NFL showcase CBS hopes will rival NBC’s most-watched Sunday Night Football, room for hours and hours of premium-priced Thursday night ads keyed to weekend moviegoing, room for a ready-made platform to launch CBS’s new fall season shows, and so on. This opening game for CBS is between the Pittsburgh Steelers and the Baltimore Ravens – normally a worthwhile ratings draw on its own merits. But with the Ravens and the NFL busily embroiled in the Ray Rice domestic violence case, that’s got to be addressed as well. And it was, on the new CBS-dominated Inside the NFL series on Showtime two days ago, if that’s any indication of what’s to come tonight.
