WGN America was an American subscription television network that was owned by the Nexstar Media Group, and was the company's only wholly owned, national cable-originated television channel. The channel in its final form under the WGN branding ran a mixture of entertainment programming (consisting of comedy and drama series, and theatrical feature films) for most of the broadcast day and a straight-news format—via a daily national prime time newscast, NewsNation—during the evening and early overnight hours.
