Shark Tank this week drew 3.9 million total viewers and a 0.6 demo rating, holding steady week-to-week, while Friday Night SmackDown (2.1 mil/0.6) did same.

Over on CBS, Undercover Boss (3.9 mil/0.4) and Magnum P.I. (5.2 mil/0.4) dipped in the demo, Blue Bloods (5.9 mil/0.5) was steady.

The CW’s Nancy Drew, ahead of next week’s finale, drew its best audience (500K) since last season’s 12th episode, while matching its season high in the demo (with a full-throated 0.1).

The Live+Same Day numbers reported in our ratings column do not reflect a show’s overall performance, given the increased use of delayed playback via DVR and streaming platforms, plus out-of-home viewing. These numbers (Nielsen fast nationals, unless denoted as finals) instead aim to simply illustrate trends or superlatives.
