Ratings: Broadcast Finals for March 21, 2013

CBS was down 9 million viewers and over 50% in the A18-49 ratings from last week, but This week, the network is airing the NCAA Men's Basketball Tournament. It may seem that CBS is hurting with its coverage, but instead of the network airing all the games, regionally on one network, all the games are national, on four networks. If you take a snapshot of the 8 p.m. hour, the combined ratings would be roughly over 11 million viewers and a 3.9 rating in the A18-49 demo.

WIFE SWAP had its season premiere to little fanfare. The reality series drew just under 5 million viewers and a 1.7 demo rating. That is not far off from the numbers SHARK TANK encores have been getting in the hour, over the last few weeks.
