WCBZ-CD (channel 22) is a low-power, Class A television station in Columbus, Ohio, United States, affiliated with the digital multicast network Cozi TV.
In 2004, the station was acquired from low-power broadcaster Crawford Broadcasting by Metro Video Productions, and was granted Class A status, thus changing its callsign to WBKA-CA.
In 2008, the station was acquired by Studio 51 Multimedia Productions, Ltd., and began operating as TV 22 Marion, offering comprehensive coverage of the events in the Marion County area, as well as other original programming.
In August 2009, the WBKA-CA call sign was changed to WMNO-CA (for "Marion, Ohio").
The station's digital signal is multiplexed: WCBZ-CD (as WMNO-CD) shut down its analog signal, over UHF channel 22, on January 7, 2015, and "flash-cut" its digital signal into operation to UHF channel 28, using virtual channel 22.
