From 1982 to 2011, WHBF-TV didn't carry either "CBS News Up to the Minute", nor its predecessor, "CBS News Nightwatch". Instead the station joined its fellow Citadel stations in signing off every night, making WHBF one of the few stations in the country to still do so. However, as of the mid-2000s, WHBF ran its transmitters all night, airing a test pattern with station identification superimposed over the pattern. Digital channel 4.2 has operated 24/7 since the Retro Television Network debut on December 1, 2008. WHBF-TV finally added "Up to the Minute" to its programming lineup in October 2011. "Up to the Minute" was replaced by the "CBS Overnight News" on September 21, 2015. The move left Iowa Public Television station KQIN as the last Quad Cities television station to sign-off.
