As primetime continues to lose viewers to the longer days and warmer springtime, Fox’s Fringe last night (1.1/3 in adults 18-49) went up a tenth from last week in its first airing since the sci-fi series was renewed for a 13-episode final season. It was one of only two series to post gains vs. their most recent originals last night. The other was NBC’s Who Do You Think You Are (1.0/4), whose Rob Lowe episode was up 25% from the previous new episode 3 weeks ago featuring Edie Falco. After surging 33% last week, Fox’s The Finder (1.1/4) was down 8% this week as it faced all-original competition in the 8 PM hour vs. all-repeats on the major nets last week.

CBS was back in originals, claiming the ratings crown for the night in adults 18-49 and total viewers but all of its series were down. Undercover Boss (1.6/6, down 11% from the fast national for its last original 3 weeks ago, 7.1 million total viewers) was once again the top program of the night in 18-49. CSI: NY (1.4/5, 8.9 million) was down 13% in the demo, while Blue Bloods (1.4/4, 10.2 million) was down 18% while ranking as the most watched program of the night. Shark Tank (1.4/5) was understandably hurt by ABC’s scheduling, down 13% from its last new episode 2 weeks ago when it returned from a long hiatus only to be sidelined for a repeat again last week. Primetime: What Would You Do? (1.1/4) was down two-tenths from last week, 20/20 (1.4/4) was up by that much. NBC’s Grimm (1.4/5) was flat with last week, while Dateline (1.1/3) was down 21%. The CW’s Nikita (0.4/2) was even with last week, Supernatural (0.6/2) was down a tenth.
