Fast National ratings for Friday, March 30, 2012.
 
Maybe last week's series-low ratings really were the result of "Hunger Games"? 
 
"Fringe" bounced back on Friday night to numbers in line with its season averages and even tied with a new "Grimm" among young viewers. Of course, even a rising "Fringe" wasn't really a factor in the Friday ratings races.
 
CBS won the night both overall and in the key demo thanks to decent, but below season averages, performances from "Undercover Boss," "CSI: NY" and "Blue Bloods."
 
Among adults 18-49, CBS averaged a 1.7 rating, nipping ABC's 1.6 rating in the key demographic. FOX moved up to third for the night with a 1.2 rating, beating NBC's 1.1 rating and the 0.5 rating for The CW.
