Once again, CBS was dominant in the ratings race, landing 13 of the Top 20 shows last week. It didn’t hurt that it broadcast the NCAA championship game, which yielded 23.43 million viewers as the week’s top program. Otherwise, ‘NCIS’ and its spinoff ‘NCIS: Los Angeles’ were typically terrific. Other shows from CBS in the Top 20 included ’60 Minutes,’ ‘The Good Wife’ and ‘The Big Bang Theory.’ The impressive part? Some of those were reruns.

ABC performed fine with ‘Dancing With the Stars’ and ‘Modern Family,’ while NBC’s ‘The Voice’ outperformed FOX’s ‘American Idol’ yet again. The bad news? Having ‘The Voice’ as a lead-in was no help for NBC’s newest reality show, ‘Ready for Love.’ Viewers apparently hated it, shedding 10 million viewers after ‘The Voice’ ended.

Over on HBO, the acclaimed comedy ‘Veep’ returned for its second season with 1.2 million viewers, while Showtime’s ‘Nurse Jackie’ claimed 582,000.
