WTHI-FM has led the Terre Haute market ratings for over twenty years. In 2007, the station celebrated 25 years in the country format.
Over the years, WTHI has raised more than $1,000,000 for the kids at St. Jude Children's Research Hospital.
WTHI-FM's former studio building, which was shared with sister station WWVR and former sister station WTHI-TV (which was co-owned with WTHI-FM from 1954 to 2005), is being demolished in December 2012 to accommodate parking for a new office building constructed behind the former WTHI building and facing Wabash Avenue.[3] The old building was constructed as a garment factory in 1906, but housed WTHI-FM and WTHI-TV from 1954 to 2012.[4] WTHI-FM and WWVR, which were later joined by new acquisitions WFNF and WFNB, moved into their new office building in August 2012;[3] this separated the stations from WTHI-TV,[4] which moved to its own new building (at 800 Ohio Street) in October 2012.[3]
