After an afternoon of comprehensive coverage on all networks of the bombing at Monday’s Boston Marathon and pre-emptions in various markets, last night’s primetime was relatively normal, with NBC the only network to make changes to its schedule. After three weeks of blind auditions, The Voice (5.1/4) finally began its battle rounds, with mentors Pharrell Williams, Sheryl Crow, Hilary Scott and Good Charlotte’s Joel Madden joining the show to help lead the judges’ teams to victory. The Voice was the most watched show of the night with 14.29 million viewers and posted its best numbers since March 12. 2012. It rose 2% from last week in adults 18-49 and viewers. The scheduled Revolution that was supposed to air at 10 PM was replaced by NBC News’ Terror In Boston (3.1/8), which was watched by 8.856 million and was up 41% from what Revolution drew last week. However, the special did not run in consistent time zones and its results likely will be adjusted in final numbers. NBC won the night in total viewers and the demo.

The CW’s Oh Sit! (0.4/1) was back for a new season at 8 PM last night. The reality show was down a tenth from its Season 1 premiere last August.

After DWTS, Castle (2.1/5) flipped the result and was up 5% from its last original April 1. Due to coverage of the bombing, ABC’s primetime was preempted in the Boston area.
