TheRabbi, the only way we will know for certain is when we get to see live plus seven, or even live plus 30 data. If you read what I've said, I have consistently pointed to live plus seven as showing basically no change, especially with all the alternate viewing platforms taken into account.
Y'all insist on playing around with the shorter time frame numbers, while the advertisers and the networks have moved on to live plus seven and CBS has moved on to live plus 30, and for new shows projections as to live plus 30. That is why shows are rarely being cancelled after a very few weeks, instead the networks are using initial and extended season orders especially for first seasons to kill off poor performers without "cancelling" them, and why shows starting to fade get shortened season orders and unfavorable time slots. (Example Person of Interest, which has yet to be set for a season premiere for a 13-episode order, and for which CBS had promised would premiere before the end of the spring season, i.e., May sweeps. A virtual impossibility at this point.)
Don't forget TAR makes money for CBS from its production costs, its overall revenue, including the syndication fees for the show worldwide, and it wouldn't surprise me if the show is whlly funded between placement fees from advertisers and the international syndication fees. This explains Survivor and Big Brother's survival while American Idol is dying.
