UPDATE PM: Insignificant downward adjustment for the CW’s Jane the Virgin premiere or The Originals, with both programs holding onto their fast national ratings among adults 18-49 and slipping just a fraction in total viewers (to 1.61 million and 1.29 million, respectively). The Voice and Dancing with the Stars were each adjusted up a tenth to a 4.0 and 2.0 in 18-49, respectively, while The Big Bang Theory (4.5) and Castle (1.9) slipped a tenth.

PREVIOUS AM: Eight years ago, as strong early reviews for the Ugly Betty pilot started rolling in over the summer, ABC changed its scheduling plans for the quirky dramedy adaptation of a telenovela, moving it from the low-profile Friday night to a Thursday 8 PM berth. The switch worked, with Ugly Betty becoming the last new scripted ABC series to open well and have legs in the Thursday 8 PM hour.

This past summer, another dramedy based on a telenovela, the CW’s Jane The Virgin from Ugly Betty exec producer Ben Silverman, had been getting some of the best reviews for a new series. In this case, the network did not change its original plans for the show, scheduled on the CW’s most challenging night, Monday, which barely registered last fall with Hart Of Dixie and Beauty And The Beast (both renewed BTW).

Paired with sophomore The Originals, relocated from Tuesday, Jane The Virgin was tasked with improving Monday. That it did. But despite a massive-for-CW-standards promo campaign, Jane‘s premiere ratings were modest, far below what other CW series had delivered when premiering behind established hits like The Vampire Diaries — where convention wisdom would have had Jane launch too. (TVD spinoff The Originals was picked as a lead-in as it is the CW’s most female-skewing show).

In the CW fast nationals, which may be inflated because of a local NFL preemption, Jane The Virgin drew 1.63 million viewers and a 0.6 in adults 18-49 (0.7 in 18-34). It built on The Originals‘ (1.34 million, 0.7) lead-in in total viewers and slipped by a tenth in the demo. The Jane debut’s 18-49 and women 18-49 (0.7) numbers are currently a time-period best since the Gossip Girl series finale in December 2012.

big-bang-theory_612x380The dust has pretty much settled for the other networks on Monday though things are about to change again as soon as The Big Bang Theory exits the night to return to Thursday post-football. For the time being, the CBS comedy rules the night. Fast nationals for the CBS lineup also may be inflated because of a local NFL preemption. Big Bang currently runs at a 4.6 rating among adults 18-49, up two tenths from its fast national last Monday, and 15.6 million viewers.

On the drama side, NBC’s The Blacklist (2.8, up a tenth from last Monday’s fast national, 9.8 million) has solidified its position as the new (old) top Monday drama, widening its Live+Same Day demo lead over newcomers Scorpion (2.4, 11.5 million), which was No. 1 in total viewers, and Gotham (2.4, 6.2 million), which was just picked up for a full season.

The other two Big 4 dramas on Monday, ABC’s Castle (2.0, 9.3 million) and CBS’ NCIS: Los Angeles (1.6, 9.1 million), finished as No. 2 and No. 3 behind Blacklist in the 10 PM hour. Castle is currently a tenth ahead of its fast national last Monday as the network is undergoing Nielsen adjustments, while NCIS: LA is on par with its rating last week but the number may be inflated. CBS’ efforts to improve its No. 3 position in the time slot with the recruitment of seasoned veteran NCIS: LA are not working so far.

voicebattleNBC’s The Voice kicked off battle rounds with a 3.8 and 13.0 million viewers. That was up 8% in the demo from the reality series’ fast national last week and the show’s largest audience since the season premiere. (Last week, The Voice was adjusted up a tenth in the final, while The Blacklist slipped a tenth.) NBC is on track to win the night in 18-49 (3.6) and total viewers (11.9 million)

Elsewhere, ABC’s Dancing With The Stars (1.9, 12.5 million) is running up a tenth in the demo from last Monday’s fast national, while Fox’s Sleepy Hollow (1.7) was flat.
