History

The station first signed on the air on January 3, 1978. WNSC debuted as the sixth full-power station aligned with SCETV, and the third public television station to serve the Charlotte area, after WTVI and Concord-based UNC-TV station WUNG-TV. Previously, SCETV programming had been seen in the Rock Hill area via low-power translator station W55AA on UHF channel 55.
WNSC-TV originates some local programming, including Piedmont Politics, and also carries national and statewide programs from PBS and SCETV. Its digital subchannels carry the South Carolina Channel, ETV World and SCETV PBS Kids.

Analog-to-digital conversion

WNSC-TV shut down its analog signal, over UHF channel 30, at midnight on February 18, 2009, the day after some full-power television stations in the United States transitioned from analog to digital broadcasts. The station's digital signal remained on its pre-transition UHF channel 15. Through the use of PSIP, digital television receivers display the station's virtual channel as its former UHF analog channel 30.
