History:: Originally on the air in 1953 as WSGN-TV, the station didn't do very well against dominant VHF stations in the market, and was sold to Johnston Broadcasting. A big contributor to my site had this to say about it: "According to Broadcasting Yearbook, there's a mention of a station sale of what was then WSGN-TV to Johnston Broadcasting, then licensee of WJLD-AM/WJLN-FM. The station changed to WJLN-TV and vanished by the late 50's." Oddly, TV Guides from the mid-50's don't mention either WSGN-TV or WJLN-TV, so questions still remain as to whether WSGN-TV even got on the air at all!; WIAT came on the air on October 17, 1965 as WBMG (BirMinGham), by Bill DuBois and minority owned by Southern Broadcasting. Prior to that time, the programming from the three major networks was cherry-picked by the only two commercial stations in the market, WBRC-6 and WAPI-13 (Now WVTM). The area lacked a CBS affiliate, which is what this station tried to become when it went on the air. WBMG and WAPI both had CBS/NBC dual affiliation in the mid-60's, mainly because WAPI didn't stop carrying CBS programming when this new UHF station came on the air.; WBMG had always struggled as a UHF battling two VHF competitors. The news never made ripples in the market, even when Tommy Charles anchored their newscasts in the 70's! The situation came to a head in 1997 when the new owners acknowledged a 1% share of the market audience during their newscasts. It ranked dead last, behind reruns. So, it was time to stop and start over with a new staff and a new image. For about a one month period, the station stopped airing local news. During those time periods (5 and 10 pm) the station ran a clock. Yes, a clock. Once a new staff was assembled, the calls changed to WIAT and local news resumed. The calls coincide with the station's new slogan (It's About Time). Despite the changes, WIAT still lagged behind the other established newscasts in the city until probably late 2008, when it finally began making ratings inroads.

In 2002, American General Media began building a new multi-pronged tower at the WTTO TV site just up the street. The new tower has room for both digital TV and FM antennas, and as part of the transition to digital broadcasting, WIAT applied to move to their digital broadcasts the new tower. That facility went on the air in the spring of 2003, with increased antenna height and a different pattern from the analog broadcasts on channel 42.; This station elected to keep analog broadcasts on until the new June 12^th deadline. At the end of March they added "Untamed Sports TV" to the 42.2 subchannel, bumping the weather info to 42.3. In the early summer of 2009 the station upgraded facilities and began showing prerecorded syndicated programming in HD. In September 2009 some in-house recorded HD promos began showing up on the air as well, and by the end of the year the station had debuted HD newscasts.; In early April 2010 this station received a construction permit for a companion digital LPTV facility, to be located on the old WDBB tower off Jug Factory Road in Tuscaloosa. This station would have had the calls WIAT-LD and would offer supplemental service on RF channel 42 for the west side of Tuscaloosa. That permit expired in April 2013; it's unknown if the facility ever went on the air or not. In May 2012 it was announced that previous owners New Vision were selling WIAT and 29 other stations to LIN TV. That deal was finished in the fall of 2012. Two years later, LIN TV was acquired by Media General, resulting in another ownership change as of December 2014.

The station was one of the earliest in the market to embrace adding a second over the air digital network, in the form of the Untamed Sports Network on —.2 subchannel; sometime in either late 2015 or early 2016 they removed the weather radar from —.3 subchannel and replaced it with the Justice Network. Untamed Sports was dropped in the fall of 2017 for Escape; they also added a fourth subchannel carrying Laff around the same time.

The station was slated to pick up the newly-relaunched Court TV in May 2019, replacing Laff on the —.4 subchannel. One year later, CourtTV Mystery replaced Escape on the —.2 subchannel.

In December 2021, the station applied to move its antenna off the American General Media "pickle fork" tower back to their own Nexstar-owned existing tower in their studio's back yard. The move of 0.14 km will come with a different antenna/pattern as well as a slightly lower antenna height. That facility signed on in August 2022.

As part of the rollout of ATSC 3.0 in the Birmingham market on WTTO and WSES, this station will take on one of the WTTO subchannel networks that will be displaced by the launch.
Note that as of 02 June 2022, the information on which channels the station will host are speculative, and subject to change.
