As part of the analog television shutdown and digital conversion, WSNS-TV shut down its analog transmitter on June 12, 2009, and continued to broadcast on its pre-transition digital channel 45. However, through the use of PSIP, digital television receivers display its virtual channel as 44. WSNS-TV's main transmitter was also transferred from the John Hancock Center to the Willis Tower.

WSNS-TV, Chicago's fourth-oldest commercial UHF station, began broadcasting on April 5, 1970. It was initially owned by a consortium of investors including Harriscope (which owned 50 percent) and the Essaness Television Corporation, from which the station's call letters arose. The transmitter and small studio were located on the 97th floor of the John Hancock Center.
