The premiere of WGN America’s series “Underground” has scored the channel’s biggest audience since the late 1990s after three days of delayed viewing.
The series debut has racked up 3.5 million viewers, including Live +3 data and encores. That’s the biggest audience for an original series premiere in the channel’s history. It also drew 1.5 million adults 25-54, WGN America’s target demo.
(WGN America and TV by the Numbers are both part of Tribune Media.)
The last time WGN America drew as big an audience was in September 1998 for a Chicago Cubs-St. Louis Cardinals game when Mark McGwire hit his 62nd home run of the season, breaking a long-standing major league record.
The previous three-day high for a series premiere was 3.2 million viewers for “Salem.”
