On January 7, 2021, Sinclair Broadcast Group (owner of WSYX and operator of WTTE & WWHO) moved the "Fox 28" intellectual property to WSYX 6.3 and converted WTTE's main signal into a primary affiliate of Sinclair-owned TBD (moving up from WTTE 28.2), as part of Columbus's upgrade to ATSC 3.0. As Sinclair effectively owns Cunningham Broadcasting (the owner of WTTE's licensed assets), this makes WTTE a de-facto TBD O&O station.
