UPDATED: Tom Selleck and "Blue Bloods" closed their season by pulling in the most viewers Friday night.

But ABC's "Shark Tank" was the favorite series of young adults. The two series' performance reflected their networks' pull on Friday: CBS had the most viewers and ABC had the most young adults.

CBS aired "Unforgettable" (7.3 million viewers), the season finale of "Hawaii Five-0" (with 9.2 million) and "Blue Bloods" (an impressive 11.8 million on a Friday). Nick Jonas came back as an evil genius on "Hawaii Five-0," and Danny (Donnie Wahlberg) found shocking information in an off-limits case on "Blue Bloods."

ABC aired a "Shark Tank" repeat (4.7 million), a new "Shark Tank" (7.4 million) and "20/20" (with 6.3 million total viewers and more young adults than "Blue Bloods").

The prime-time averages in total viewers: CBS with 9.4 million, ABC with 6.1 million, NBC with 4.1 million, Fox with 1.4 million for a repeat of the "24: Live Another Day" premiere, and The CW with 1 million.

NBC aired "Dateline" (5.6 million), "Grimm" (4.8 million) and "Hannibal" (2 million). The CW offered a new "Whose Line Is It Anyway?" (1.5 million), a "Whose Line" repeat (1.1 million) and "Hart of Dixie" (760,000 viewers).
