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.
WBAY-TV
In 1991, CBS purchased the assets of Midwest Television to acquire its long-dominant affiliate in Minneapolis–Saint Paul, WCCO-TV. Midwest also owned channel 2's longtime competitor, WFRV. CBS considered WBAY a strong affiliate, and tried to sell WFRV and their Escanaba, Michigan-based satellite station, WJMN-TV, after the deal with Midwest closed. However, after FCC rules were relaxed at the time to allow one company to own more stations, the network decided to keep the two stations as a result and switched WFRV/WJMN to CBS in 1992 (CBS sold WFRV/WJMN to Liberty Media in 2007, the stations are now owned by the Nexstar Media Group).
