WCBS-TV
On October 21, 2014, CBS and Weigel Broadcasting announced the launch of a new digital subchannel service called Decades, scheduled to launch on all CBS-owned stations on May 25, 2015, including on WCBS-TV on channel 2.2. The channel is co-owned by CBS and Weigel (owner of CBS affiliate WDJT-TV in Milwaukee), with Weigel being responsible for distribution to non-CBS-owned stations. It airs programs from the extensive library of CBS Television Distribution, including archival footage from CBS News. On September 3, 2018, Decades was replaced on 2.2 by Start TV.
WGEN-TV
W38AA in Marathon and W39AC in Key West are listed as having WSBS-TV as their primary station, although in the past the two stations had retransmitted Miami CBS owned-and-operated station WFOR-TV (channel 4). Their respective digital companion channels W08ED-D (under construction) and W12DI-D are shown as having WGEN-TV as the primary station, and 12.1 is shown on WGEN's map as an additional channel for Key West (though only analog channel 21 is shown for Marathon). Because Key West and even Marathon are well within the broadcast range of both WSBS and WGEN, it is unclear why this would be necessary (or in Key West, useful at all), given the total flatness of the terrain and water and the complete lack of other obstructions like tall buildings. The only advantage for WSBS is to continue to be seen on analog television.
