WGN America (formerly known as "Superstation WGN" or "WGN Superstation") is a Chicago-based American superstation for WGN-TV, owned by Tribune Broadcasting Company. WGN America offers its national programming across North America without the CW network programming that is carried on the Chicago area feed. It is the only remaining national superstation after TBS became a regular cable channel on October 1, 2007 (although WGN is still not available in most New England cable services).
