USA, which was successful in attracting a younger-audience profile for “Mr. Robot” last summer, is off to a good start in doing the same with “Colony.”

Last Thursday’s second episode of the sci-fi drama from Carlton Cuse (“Lost”) and Ryan Condal (“Hercules”) was up vs. its Jan. 14 premiere across the board in Nielsen’s “live plus-3” estimates — including by 4% in adults 18-49 (1.17 million vs. 1.12 million) and by 9% in adults 25-54 (1.34 million vs. 1.23 million). And that premiere stood as USA’s top-rated series launch in 18-49 (0.88 rating) and 25-54 (1.04) in five years, and ranked fifth among the week’s top basic cable dramas in both categories.

“Colony” has proven to be an especially big gainer in delayed viewing, and its second episode spiked from “same-day” to “live plus-3” by nearly 140% in both 18-49 and 25-54 and by 116% in total viewers (2.72 million vs. 1.26 million).

In addition to the 3.4 million people who watched one of the two pilot airings on Jan. 14, more than half a million people sampled the episode during a targeted, two-week pre-linear release on select digital platforms including USAnetwork.com, Hulu, the USA Network App and VOD.

Set in the very near future, “Colony” centers on one family’s struggle to survive and bring liberty back to the people of an occupied Los Angeles. Josh Holloway stars as former FBI agent Will Bowman and Saray Wayne Callies stars as his wife, Katie. The series is a co-production between Legendary Television and Universal Cable Productions. Nelson McCormick also executive produces.
