Every tenth counts.

For Fringe, that statement rings true and Friday's winter finale did just that. The Fox drama improved in total viewers and the adults 18-49 demographic from the last original to average 3.1 million and a 1.2 rating. The cult favorite leaves the smalls screen for a four-week break before returning with eight back-to-back originals beginning in March.

Fox tied with NBC for third place on the night with a 1.3 primetime average, thanks to Kitchen Nightmares (3.5 million, 1.5) also jumping in the ratings.

ABC's Shark Tank (5.9 million, 1.8) matched a series high in the key demo at 8 p.m., improving on the network's 18-49 average by 80 percent last year.

The network placed second with a 1.5 demo average, behind first-place CBS.

CBS' Undercover Boss (8.6 million, 1.9) placed No. 1 in vieweership and the 18-49, a drastic improvement in the latter category compared to previous time slot occupant A Gifted Man (9.1 million, 1.3). The Patrick Wilson-led medical drama, which had rose last week after moving to its new time period, dropped down two-tenths in the demo this week. Blue Bloods (11.2 million, 1.7) improved in all key categories compared to last week.
