The station's channel 19 signal is also used by Chicago's WGN-TV and WXMI in Grand Rapids, Michigan, causing interference between it and those two stations in the easternmost portions of their coverage area, mainly in Walworth County, which is just outside the Madison market (though WXMI's signal is limited by the Kettle Moraine range west of Jefferson County).

On October 18, 2010, the station also began airing its flagship syndicated programs Jeopardy! and Wheel of Fortune in HD.
