WTHI-TV first signed on the air on July 22, 1954. It was the first television station in the Terre Haute
market. It was founded by local businessman and
Indianapolis Motor Speedway owner
Tony Hulman, owner of radio stations WTHI (1480 AM, now
WPFR), and
WTHI-FM (99.9). Channel 10 has been a CBS affiliate since its sign-on; however, it initially carried programming from
NBC,
ABC and the
DuMont Television Network as well through secondary affiliations. WTHI-TV originally operated from a studio facility at 918 Ohio Street (at the intersection of South 9th and Ohio streets) in downtown Terre Haute, which also became occupied by WTHI-FM upon the television station's sign-on (the building was originally constructed in 1906 to house a garment factory). WTHI lost the DuMont affiliation when the network ceased operations in August 1956; NBC programming moved to the city's second television station,
WTWO (channel 2), when it signed on the air in September 1965. The station exclusively aligned with CBS when the ABC affiliation moved to WIIL-TV (channel 38, now
WAWV-TV), when it signed on in April 1973. Local programs airing on the station during its earlier history featured
Jerry Van Dyke of
Coach and
My Mother the Car fame, and "Captain Jack" Hanes, whose most famous guest was eventual
Boston Celtics legend
Larry Bird. WTHI was a secondary affiliate of
UPN when the network launched on January 16, 1995, carrying its programming immediately after CBS late night. Rare for those arrangements with UPN, it continued until the network ended operations and merged with the WB in September 2006 to form
The CW, as no full-power or low-power stations came on the air in the market through that time. The Hulman family continued to own WTHI-TV until 1998, when they sold the station to
Emmis Communications. Emmis Communications announced the sale of its 16 television stations on May 15, 2005, in order to concentrate on its radio properties. Emmis sold WTHI-TV to the
LIN TV Corporation in August 2005, placing it under common ownership with LIN's three other CBS affiliates in Indiana:
WANE-TV in
Fort Wayne,
WLFI-TV in
Lafayette), and at the time,
WISH-TV in
Indianapolis (the affiliation has since moved to
WTTV in January 2015). In October 2012, the station relocated its operations to a new facility located one block west of its original studios, at 800 Ohio Street in downtown Terre Haute; the original studio building, which was also shared with former sister stations
WWVR (105.5 FM) (which, along with WTHI-FM, remains owned by Emmis Communications), was demolished in December 2012 to accommodate parking for a new office building being constructed nearby. The move completely separated WTHI-TV from WTHI-FM, which had moved into the new office building that August. The merger was completed on December 19. Shortly thereafter, after an aborted merger plan with
Meredith Corporation, Media General announced on January 27, 2016, that it was being acquired by
Nexstar Broadcasting Group with the new company named "Nexstar Media Group". As Nexstar already owns WTWO (and operates
Mission Broadcasting-owned WAWV-TV) and since the Terre Haute market is too small to allow duopolies in any case, in order to comply with FCC ownership rules as well as planned changes to rules regarding same-market television stations which would prohibit future
joint sales agreements, the company was required to sell either WTWO or WTHI to another company. On March 4, 2016, Nexstar and Mission declared their intentions to keep WTWO/WAWV and sell WTHI to another company; on June 13, 2016, it announced that WTHI and four other stations would be acquired by Heartland Media, through its USA Television MidAmerica Holdings
joint venture with MSouth Equity Partners, for $115 million. The deal was consummated upon the approval of Nexstar's merger with Media General on January 17. On October 1, 2019,
Allen Media Broadcasting, a subsidiary of
Los Angeles–based
Entertainment Studios, owned by
Byron Allen, agreed to purchase 11 stations from Heartland, including WTHI-TV, for $290 million. The sale of the Heartland stations was approved by the FCC on November 22, 2019, and it was completed on February 11, 2020. On June 1, 2025, amid financial woes and rising debt, Allen Media Group announced that it would explore "strategic options" for the company, such as a sale of its television stations (including WTHI). On August 8, 2025, it was announced that AMG would sell 12 of its stations, including WTHI, to
Gray Media for $171 million. The sale of WTHI was completed on March 27, 2026, marking Gray's entry into the Terre Haute market. ==Subchannel history==
