WSFJ-TV

Owned and operated by the Ion Media subsidiary of the E. W. Scripps Company, the station maintains studios on North Central Drive in Lewis Center, Ohio.

Prior to the arrival of WSFJ, Columbus-area cable systems imported the signals of independents from nearby areas, such as WXIX-TV in Cincinnati, WUAB in Cleveland and WTTV in Indianapolis.

In the fall of 1980, WSFJ began running secular programming such as Independent Network News and New Zoo Revue during the weekdays, along with Wild Kingdom and other hunting and wildlife shows on Saturdays.

However, the schedule remained predominantly Christian, and its policy regarding secular programming was very conservative so as not to offend the sensibilities of its mostly fundamentalist and Pentecostal viewership.

In 2005, WSFJ began to acquire some family-friendly programming separate from its affiliation with Pax/i and rebranded the station as GTN51—short for "Guardian Television Network".

[6] As a TBN-owned station, WSFJ served as a pass-through for the TBN national feed with virtually no local programming.

TBN has long been known for buying existing stations in order to get must-carry status on local cable systems.

Ion Media has pursued a new strategy since 2018 of giving Ion Life a primary channel placement (mainly involving purchases and shuffles related to the incentive auction) in order to require local cable and satellite providers to offer the channel under must-carry provisions.
