WNTZ's master control operation was located in Lafayette at the studios of then-sister stations KADN-TV and KLAF-LD from 1991 until July 2015.

WNTZ was granted its license to Louisiana state senator Bill Atkins of Jonesville, via his company MSLA Broadcasting, on January 31, 1985, and signed on the air on November 16.

To alleviate this problem, the original transmitter and broadcast equipment was sold to future WNTZ owner Communications Corporation of America and moved to sign on WGMB-TV in Baton Rouge.

This was done in order to build a new tower and transmitter site in the small farming community of Frogmore, in neighboring Concordia Parish, Louisiana.

Similar to its operations in Alexandria, Delta Media, then later White Knight and Communications Corporation of America, paid monthly rent for use of the original studio to the building's owners.

Shortly after signing on, K47DW began airing commercials and legal identification separately from KADN, renaming its brand as "Fox 47".

Then the WNTZ operation moved a third time to rented space along Parliament Drive in the Noles-Frye building, a local real estate agency.

Thomas created CCA when he signed on Fox affiliate WGMB in Baton Rouge from the purchase and move of the original transmitter for WNTZ.

CCA eventually purchased KADN in Lafayette from Delta Media outright in 2004, after a long-term Local marketing agreement (LMA).

White Knight considered relocating WNTZ's main transmitter tower back to Mississippi at a site east of Natchez such that the station could serve as an over the air affiliate for more viewers in the South and Central Mississippi areas, making its Frogmore transmitter a translator station.

This was coupled with the long-standing thought by its competitors and some Alexandria viewers that WNTZ was "non-local" station, due to its license in Natchez and being corporate-owned.

In turn, Fox owner News Corporation announced the creation of MyNetworkTV for those stations left out in the cold due to The CW merger.

On September 9, 2013, due to the return of The Arsenio Hall Show to late night television on WNTZ, MyNetworkTV was moved to air from 11 p.m. to 1 a.m.

During the bankruptcy proceedings, White Knight asked to merge many of the stations it owned, including WNTZ, into the fold of its parent company, Communications Corporation of America.

In August 2007, WNTZ debuted Fox News Louisiana AM in Alexandria to counter KALB and KLAX's national morning shows.

Produced out of sister station WGMB in Baton Rouge, the newscast featured "local" news segments and eight weather updates an hour.

The station's signal is multiplexed: The following two translators had their licenses canceled, due to the transition from analog to digital transmission.

Immediately after American Idol ended, WNTZ ran "The Star-Spangled Banner" (the footage was dated from 1940, so the flag in the clip had only 48 stars, ironically coinciding with the channel number) and then the analog signal shut off.
