But ABC had more success with recounting the sensational murder trial and Arias' conviction. The "20/20" hour focused on both the rescued Cleveland women and Arias. That hour drew 5.8 million viewers and ran second to the season finale of CBS' "Blue Bloods" with 10.3 million viewers. But "20/20" had more young adults.
The "Dateline" hour on Arias, called "Obsession," pulled in 4.6 million at 9 p.m. It ran third in the hour to CBS' "Vegas" with 7.2 million viewers and ABC's "Shark Tank" with 6.3 million. "Shark Tank" was the night's most popular program with young adults.
Which brings us to cancellations. Yes, "Vegas" may have had the most viewers at 9, but it ranked third to "Shark Tank" and "Dateline" in bringing in young viewers. So CBS has axed the Dennis Quaid-Michael Chiklis drama, according to several reports.
"Rock Center With Brian Williams" is gone at NBC. It ranked third, with 4.8 million viewers, at 10 p.m. behind "Blue Bloods" and "20/20."
CBS easily won the 8 p.m. hour with "Undercover Boss," which drew 7 million viewers and the most young adults in the time slot.
The prime-time averages: CBS with 8.2 million viewers, ABC with 5.1 million, NBC with 3.9 million, Fox with 2.9 million and The CW with 790,000. But ABC edged CBS for the win in the 18-to-49 age group.
