March 2021, Bounce TV was launched on 4.2, while Laff moved to 4.6. WTMJ-DT3 (Ion Mystery) In early July 2009, WTMJ launched digital channel 4.3 as an affiliate of TheCoolTV, becoming the first full-power station to carry the music video and concert programming-focused network as a digital subchannel; it was later carried by stations owned by the Sinclair Broadcast Group (except for WVTV (channel 18) and WCGV-TV locally due to WTMJ's carriage of the network) and LIN TV; WTMJ's Green Bay sister station WGBA also added TheCoolTV in November 2010. The subchannel, which locally had its on-air playlist customized by WTMJ, was co-branded with WTMJ-TV's sister radio station WLWK-FM (now WKTI), which then had a format spanning a variety of decades. In September 2011, Journal Communications filed a $257,000 lawsuit against TheCoolTV's parent company Cool Music Network, LLC, alleging non-payment of broadcast services since before June 2011. Because of the dispute, WTMJ replaced TheCoolTV with the Live Well Network on October 1 (WGBA, meanwhile, replaced it with MeTV on that date). WTMJ eventually converted the channel's aspect ratio to 480i widescreen, optimized for 16:9 displays, in line with LWN's default screen presentation; select Live Well programming (consisting of Motion and Deals) was broadcast in high definition during Saturday late night slots on the station's main channel until the network was removed. On January 12, 2015, one week before Live Well Network was to originally discontinue operations entirely (its distribution would instead be relegated exclusively to ABC Owned Television Stations outlets after a three-month reprieve from its planned nationwide shutdown), it was replaced on WTMJ-DT3 with the NBC-owned subchannel service Cozi TV. Through the same agreement with Katz Broadcasting under which the station affiliated WTMJ-DT2 with Laff, WTMJ-TV was listed as a future affiliate of Escape. It was not added right away, as WTMJ's agreement with NBC to carry Cozi had not yet expired and the station did not want to compromise picture quality with a fourth subchannel before a later multiplexer upgrade. Instead, WTMJ and DTV America's WTSJ-LP (channel 38) arranged a trade where Escape was carried on that station's third subchannel until November 2016, then was removed until January 1, 2017 when WTMJ's Cozi affiliation expired. WTMJ picked up Escape that day, with WTSJ taking Cozi for their third subchannel on January 15. Cozi then established another affiliation on June 22, 2017 with WIWN (channel 68.1), acquiring the Charter
