[3] From studios on Central Street,[4] WKCH-TV made its debut on the evening of December 31, 1983—with introductory remarks that then had to be repeated because the audio was not broadcast the first time.

[9] Officials alleged that Brumlik's ownership of TeleOnce in Puerto Rico was a front for two important Latin American media men: Remigio Ángel González, reported to be a business partner with Manuel Noriega in a Panamanian television station, and Julio Vera Gutiérrez, a Peruvian citizen.

[10] In November 1989, a motion was filed by WKCH-TV's trustee to cancel the proposed sale to Brumlik, citing the uncertainty created by the money laundering case.

[14] In 1993, FCVS received an "offer it could not refuse" from Ellis Communications and sold its broadcast holdings: WKCH-TV, WACH, and WEVU-TV in Naples, Florida.

[15] Ellis made further improvements, including changing the call sign to WTNZ and relocating the studio to Executive Park Drive in 1994.

[18] Gray kept its existing duopoly of WVLT-TV and WBXX-TV and sold WTNZ to a third party;[19] on August 20, 2018, Gray sold WTNZ, along with fellow Fox affiliates WFXG in Augusta, Georgia, WPGX in Panama City, Florida, and WDFX-TV in Dothan, Alabama, to Lockwood Broadcast Group (owner of independent station WKNX-TV).

[23] After 10 years, the WTNZ-WATE collaboration ended, and WTNZ entered into an agreement with NBC affiliate WBIR-TV to produce local news.
