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
The station's digital channel is multiplexed:
On October 21, 2014, CBS and locally based Weigel Broadcasting announced that they would partner to launch Decades, a digital subchannel network focusing on classic television series from the 1950s to the 1980s sourced from the CBS Television Distribution library, along with some historically-focused original programming using archival footage from CBS News; most of CBS Television Stations' outlets serving as charter affiliates, with Weigel being responsible for distribution to non-CBS-owned stations. The network soft launched in the Chicago market on WBBM digital channel 2.2, when that subchannel launched on February 1, 2015, with the network making its formal national debut four months later on May 25. Decades moved to WCIU-DT4 on September 3, 2018, with WBBM-DT2 becoming the home of a second Weigel/CBS concept network known as Start TV, which specializes in airing procedural dramas with women in the lead roles.
