Lip Sync Battle has climbed to 3.2 million viewers in Live+3, making it the most-watched series premiere in Spike TV’s history and the second-most watched original series telecast. The LL Cool J-hosted competition also tallied a 2.0 rating with adults 18-49, the second-highest ever for an original series in channel history – good news for a network trying to broaden its audience.

Thursday’s unveiling at 10 PM had delivered 2.2 million viewers Live+Same Day, making it the most-watched nonscripted series debut in the network’s history and its largest average audience in the slot in more than eight years. Lip Sync Battle also delivered the highest rating with adults 18-49 in network history for a nonscripted series debut (1.3 adults 18-49). It was the highest-rated series premiere in Spike history among women 18-49 (1.5) and women 18-34 (1.4); the network noted last week that the premiere’s 18-49 audience was 56% female

At the time, Spike President Kevin Kay said, “We are incredibly encouraged by the balanced audience of the premiere as we continue our mission to target a broad viewership.”

Delayed viewing stats are far more relevant for this series in particular, given its auspices. Stephen Merchant’s lip synch battle with Joseph Gordon-Levitt on The Tonight Show back in September 2013, for example, has amassed nearly 43 million views on YouTube.
