This week it’s all about the acronyms when it comes to ratings and CBS. Fueled by a strong performance from the title game of NCAA Tournament plus some NCIS, CSI and a bit of the Masters’ final round Sunday, the network took the top spot for Week 29 of the 2012-2013 season. It’s the fourth week in a row the network has been No. 1 in total viewers and adults 18-49 and adults 25-54. For the week of April 8-14, CBS had a 2.4/7 among in 18-49 with 10.826 million total viewers on average, according to Nielsen.

Not only was the April 8 NCAA final between Louisville and Michigan the highest-rated program of the week with an 8.4, but it was the most watched with 23.426 million tuning in. CBS also had the second- and third-most-watched shows the week with NCIS and NCIS: LA on April 9 pulling in 17.216 million and 14.103 million, respectively. In total viewership, the April 11 rerun of The Big Bang Theory actually beat all other scripted shows on the other networks with 11.435 million. Unlike ABC, NBC, Fox and the CW, CBS had ratings, share and viewership growth when compared to the same week of the 2011-2012 season. Still, CBS was down from the 2.7/8 among adults 18-49 and 11.256 million watching from the frame before, when the NCAA Final Four was on and so was the 48th annual Academy Of Country Music Awards.

As CBS took a slip from the heights of the previous frame, the other networks moved into new positions. With American Idol flexing muscle and making some gains, controversial new Glee up strong and the return of an almost all new Sunday animation block, Fox broke out of its tie with NBC in the previous frame to solidly take the No. 2 spot in the demo (1.9/6) and total viewers (6.046 million). That’s up from the 1.7/5 and 5.145 million viewers from Week 28 and the second week in a row of ratings growth for Fox. With The Voice hitting a season high on April 8, Fashion Star hitting a five-week high on April 12 and freshman Hannibal growing in its second week over its premiere, the otherwise struggling NBC was clawing in. Nonetheless, while not losing anything ratings-wise from the last frame, the network didn’t gain anything either and got no real love from the premiere of its new reality show Ready For Love on April 9. In the end, NBC found itself in third place in 18-49 this frame with its 1.7/5. In viewership, the network slipped a bit from Week 28’s 5.235 million to 5.073 million this past week. (more…)
