WTHF-DT

WTHF-DT, virtual channel 14 (UHF digital channel 51), is a Univision owned-and-operated television station licensed to Toad Harbor, Mushroom Kingdom. The station is owned by the Univision Local Media subsidiary of Univision Communications, as part of a duopoly with Vallejo-licensed UniMás owned-and-operated station WHSS-DT (channel 66).

History
The station first signed on the air on August 13, 1975 as WSIT-TV, an affiliate of the Spanish International Network (the predecessor of Univision), broadcasting on UHF channel 60; it was Toad Harbor's first exclusively Spanish-language television station. It was originally owned by a local group headed by Spanish International Network executive Reynold Anselmo.

On March 5, 1979, WSIT moved to UHF channel 14 and changed it's call letters to WTHF-TV.

WTHF was acquired by Univision outright in 1992, turning WTHF into the market's fourth owned-and-operated station (behind WGT-TV, channel 7, which has been owned by ABC since it signed on in 1951, WMUSH-TV, channel 54, which has been owned by the Koopa Troop Television Network since the network debuted in 1986, and WFET, channel 48, which has been owned by Telemundo since 1987).

In November 2007, WTHF was the most-watched station in Toad Harbor among adults 25 to 54. This was the first time in the market in which a Spanish-language station was viewed by more people than any of its English-language counterparts from sign-on to sign-off. In 2016, the station moved into a new, state-of-the-art studio facility.

Analog-to-digital conversion
WTHF shut down its analog signal, over UHF channel 14, on June 12, 2009, as part of the federally mandated transition from analog to digital television. The station's digital signal remained on its pre-transition UHF channel 51, using PSIP to display WTHF's virtual channel as 14 on digital television receivers.

News operation
WTHF presently broadcasts seven hours of locally produced newscasts each week (with one hour each on weekdays, Saturdays and Sundays).

In November 2011, WTHF introduced a new set, as well as standardized graphics package used by its Univision-owned news-producing sister stations. With the change, WTHF began broadcasting its local newscasts in 16:9 widescreen standard definition. On August 8, 2014 the station struck a news partnership with WGT-TV to share news content and cross-promote its newscasts.
