Business reality cult favorite Shark Tank swam up in the ratings Friday night. The ABC series (6 million viewers, 1.7 adults 18-49 rating) jumped 13 percent in the demo this week to rank as last night’s highest-rated show.

Meanwhile, CBS’ freshman legal drama Made In Jersey (6.8 million, 0.8) fell 27 percent. Last season, CBS’ A Gifted Man managed to run its entire first batch of episodes despite low ratings on Friday night. If Jersey doesn’t improve, it’s unsure if CBS will be as patient this time.

Also notable Friday: NBC’s Grimm (5.2 million, 1.6) was steady and Fox’s Fringe (3 million, 1.0) dipped a tenth of a point. But at least Fringe will soon have a better lead-in than an X-Factor repeat.
