Fast National ratings for Friday, October 4, 2013.
 
The Friday ratings race is back to where it was for most of the spring: "Shark Tank" was the night's top show in the key demographic and led ABC to a slim victory among young viewers, while "Blue Bloods" was easily the night's top show in total viewers and led CBS to a dominant victory overall.
 
Overall, CBS was mostly consistent, with "Hawaii Five-0" posting small gains and the other two dramas dropping a little. Both "Undercover Boss" and, particularly, "Blue Bloods" also dropped among young viewers, though "Hawaii Five-0" was steady. 
 
For ABC, although "Shark Tank" was down week-to-week, "Last Man Standing" posted small gains both overall and the demo, but didn't help the still-sluggish "Neighbors."
 
Also joining the "small declines" group was FOX's "MasterChef Junior."

Among adults 18-49, ABC averaged a 1.5 rating for Friday night, edging out CBS' 1.4 rating in the key demographic. NBC's 1.1 key demo rating, FOX's 1.0 key demo rating and the 0.4 key demo rating for The CW followed.
