On October 21, 2014, CBS Corporation and Weigel Broadcasting announced the launch of the network, then known as Decades, with plans to debut the network in 2015. Through its part-ownership by CBS Corporation, Decades announced that owned-and-operated stations of the CBS television network would serve as its initial charter network affiliates.
The network was the first national multicasting venture by CBS News and Stations. The group did not carry subchannels on any of its television stations prior to 2013. And at the time of the Decades announcement, only three of its stations even maintained subchannels (CBS O&Os WCBS-TV in New York City and KYW-TV in Philadelphia carried rolling news channels under the “CBS Plus” brand on their respective secondary subchannels, while independent station KTXA in Dallas–Fort Worth, Texas carried MeTV on its second subchannel). In addition, CBS Television Distribution had already maintained a content distribution agreement with Weigel Broadcasting’s classic television network MeTV, which sourced much of its programming from that library.
On January 13, 2015, Weigel Broadcasting confirmed that its Milwaukee CBS affiliate WDJT-TV would carry the network on its fourth digital subchannel. It would replace the digital news service TouchVision.
Decades officially launched at 7:00 a.m. Eastern Time Zone on May 25, 2015, with the series premiere of Through the Decades as its inaugural telecast. At the time, the network was available in over 45% of all American households with a television set.
On March 27, 2023, Decades re-branded as Catchy Comedy, focusing on primarily classic sitcoms and sketch comedy variety shows weekdays with comedy marathons on weekends
