Fast National ratings for Friday, April 18, 2014.

New episodes of "Shark Tank" and "20/20" helped ABC cruise to an easy Friday win among young viewers, while CBS rode a new "Unforgettable" and a "Blue Bloods" repeat to an overall win.

Beyond that, Friday featured only minor variations. FOX's "Kitchen Nightmares" was down in its second week, while "Hannibal" took advantage of a "Dateline" lead-in to get a small bump. The CW's "Hart of Dixie" and "Whose Line" both shed viewers as well.

[CBS notes that its scheduled was delayed a local telethon for 9 percent of the country. Take that as you will.]
