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.
WBBM-TV
For most of the time since the mid-1990s, WBBM-TV has been one of CBS' weakest owned-and-operated stations, generally rating behind WLS-TV, NBC owned-and-operated station WMAQ-TV (channel 5) and at times behind WGN-TV and Fox-owned WFLD (channel 32), despite the strong ratings of CBS' daytime and prime time shows in recent years. The station made some viewership gains during 2009, but has generally remained in third place in the ratings, partially due to its digital signal on low-band VHF channel 3, which operated at a lower power than the Chicago market's other full-power television stations in order to avoid interfering with the analog signal of WWMT in Kalamazoo (the same station that indirectly forced the 1953 allocation switch from channel 4 to channel 2).
