Last night’s series premiere of Syfy’s new drama Defiance drew 2.7 million viewers and 1.3 million adults 18-49 to become the channel’s most-watched scripted series premiere in adults 18-49 and 18-34 (479,000) in seven years, since the 2006 debut of Eureka. The two-hour Defiance opener also delivered Syfy’s top performance in total viewers and adults 25-54 (1.4 million) since 2009 (Warehouse 13). Defiance was developed as a TV series and companion Trion Worlds video game, which has logged more than 6 million hours of gameplay since its April 2 launch. Defiance is NBCUniversal’s biggest day-and-date launch ever, premiering in more than 55 countries April 15-16 including the UK, Canada, Germany and France. Beginning next Monday, Defiance will assume its regular 9 PM time period, followed on Monday, April 29 by the season return of Warehouse 13 at 10 PM.
