“Underground” arrived with a bang on Wednesday night, setting a new ratings record for WGN America.
The 10 p.m. premiere of the Underground Railroad drama pulled in 1.42 million viewers. Over four airings on Wednesday night, the show managed to draw 2.5 million viewers, making it the most viewed premiere for an original series in the network’s history.
Its 1.4 million viewers means “Underground” bested the series premieres of Showtime’s “Billions” by 57 percent, HBO’s “Vinyl” by 86 percent, and the FX series”Baskets” by 37 percent. That also means “Underground” is the fifth highest-rated premiere for a scripted series premieres on cable this broadcast season.
