Syfy's biggest original launch in years, Defiance, premiered on Monday night -- and brought in solid 2.7 million viewers in its first outing.
That marks the network's best showing in total viewers since the 2009 opener of top-rated original Warehouse 13. Among adults 18-49, the two-hour premiere fared even better. The 1.3 million haul in the key demo was a network best since Eureka in 2006.
In other demographics, Defiance averaged 1.4 million adults 25-54 (1.4 million) and 479,000 adults 18-34. Over the course of Monday and Tuesday nights, the series will premiere in over 55 countries -- the biggest day-and-date launch in NBCUniversal history.
