The Retro Television Network was previously seen on WGRZ-DT3. The 2.3 channel was removed in September 2011 with no replacement, in order to provide better picture quality to both the DT2 and the main WGRZ signal. The DT3 subchannel had never gained significant cable carriage and by that time, much of the programming was being duplicated by WBBZ-TV. Although the DT2 subchannel has achieved significant cable penetration dating to its time as a Weather Plus outlet, Universal Sports itself converted to a cable and satellite-only service in January 2012 as part of Comcast's overhaul of the NBC Sports division. WGRZ-DT2 then became an affiliate of Antenna TV, competing with WBBZ-TV. The DT2 subchannel returned to weather on January 1, 2014, affiliating with WeatherNation TV with the local branding "StormTeam 2 WeatherNation". Antenna TV then moved to a reactivated DT3.
