The Tuesday premiere of Syfy's new original series Warehouse 13 was the network's biggest launch of a scripted series since Eureka in 2006, pulling in a total audience of 3.5 million viewers and putting the newly rechristened network on top among its peers for the night, the network announced.
The show's ratings made Syfy the most-watched ad-supported cable network in the 8 p.m. to 11 p.m. prime-time period.
The debut of the series surpassed last October's premiere of Sanctuary by 29 percent in total viewers and 20 percent among adults aged 18-49.
Warehouse 13 reported a household rating of 2.5, with an audience of 1.3 million among adults aged 18-49 and 1.7 million aged 25-54.
Warehouse 13 drew the third-highest total viewership for a Syfy original series, trailing only the series premieres of Stargate Atlantis (4.2 million total viewers on July 16, 2004) and Eureka (4.1 million total viewers on July 18, 2006).
When final DVR viewing is included, Warehouse 13 will increase its viewership and may surpass one or both of those premieres.
