WAZE-TV originally broadcast its digital signal on UHF channel 20 just before that station shut down permanently in 2011.
The low-power channel 20 was founded on September 22, 2011, as WYYW-CD, and became a MeTV affiliate two months later. This happened three weeks after CBS affiliate WEVV-TV began broadcasting Fox network programming on its second digital subchannel.
On December 12, 2012, WYYW-CD and WTSN-CD swapped call signs. The original WTSN-CD became WYYW-CD, while the original WYYW-CD became WTSN-CD.[2]
The station became a Heroes & Icons (H&I) affiliate on October 23, 2014, while MeTV relocated to WFIE-DT3; five days later, MeTV moved to WFIE-DT2. Then on January 17, 2015, WTSN replaced its H&I affiliation with Heartland's E/I programming repeats from its sister station on Saturday mornings because of its Sunday religious and local programming up until the Heartland affiliation with WYYW-CD ended.
On October 25, 2019, WTSN dropped the H&I affiliation, replacing it with Antenna TV.[3]
