Fast National ratings for Friday, May 6, 2011.
 
FOX's "Fringe" celebrated its third season finale by dropping (a miniscule amount) with young viewers and delivering yet another time period low in total viewers. CBS' "Flashpoint" celebrated its latest American premiere with unimpressive numbers. And yet both FOX and CBS were able to claim small shares of victory on a sluggish Friday.
 
Among adults 18-49, there was a three-way tie for the top spot with FOX, CBS and ABC all averaging a 1.4 rating in the key demographic. NBC was right behind with a 1.3 rating, while even The CW's 0.9 rating wasn't far off.
 
Overall, CBS averaged 8.77 million viewers and a 5.6 rating/10 share, claiming a commanding victory over the 4.87 million viewers for ABC and NBC's 4.83 million viewers. FOX's 2.2/4 and 3.48 million viewers finished fourth, with The CW's 1.3/2 and 2.04 million viewers good for fifth.
 
8 p.m. - "Flashpoint" returned to CBS' schedule with 6.89 million viewers, tops in the 8 p.m. hour, though the Canadian procedural's 1.1 rating among adults 18-49 was only good for third in the slot. ABC's "Shark Tank" was second overall with 4.48 million viewers and second in the demo with a 1.2 rating.
