Meanwhile, Walking Dead's Season 3 finale delivered an all-time high of 12.4 million viewers and 8.1 million in the adults 18-to-49 demographic, up 36 percent and 31 percent, respectively, from last season's finale.
On History, The Bible's two-hour finale averaged 11.7 million viewers and 3.8 million in the demo, up 14 percent and 12 percent, respectively, from last week. The Bible also edged out The Walking Dead head-to-head in the 9 o'clock hour, 12.33 million vs. 12.29 million.
With most broadcast networks in repeat mode, CBS easily won the night, thanks to a March Madness overrun that delayed prime time by 41 minutes. The network averaged 10.6 million viewers and a 2.5 rating.
ABC's Revenge (5.4 million, 1.5) dropped 17 percent, while Red Widow (4.1 million, 1.0) tied a series low.
On NBC, All-Star Celebrity Apprentice (4.6 million, 1.4) hit a series low as well.
