It began broadcasting operations on May 7, 2003 as a full-time satellite of UPN affiliate WFXU in Live Oak, Florida. Although that station had become Tallahassee's UPN affiliate a year earlier, its signal was not nearly strong enough to cover the entire market and WTLF was intended to make up for this shortfall in coverage. WFXU had originally been established back in 1998 as a full-time satellite of WTLH for the same reason. WTLF was one of the first stations in the United States to sign-on as a digital-only station with no analog counterpart. Originally, this station was owned by KB Prime Media but operated by Pegasus Communications under a local marketing agreement. Pegasus declared bankruptcy in June 2004 over a dispute with DirecTV over marketing of the direct broadcast satellite service to rural areas. On April 1, 2005, WFXU/WTLF switched to The WB through The WB 100+. As a result, UPN promptly signed with WCTV which launched a new second subchannel to carry the network. Prior to this, The WB was carried on a cable-exclusive station which was operated and promoted by ABC affiliate WTXL-TV in partnership with The WB 100+. On January 24, 2006, CBS and Time Warner announced that they were "merging" their UPN and WB networks to create The CW effective September 2006. On February 22, News Corporation announced it would start up another new network called MyNetworkTV. This new service, which would be a sister network to Fox, would be operated by Fox Television Stations and its syndication division Twentieth Television. MyNetworkTV was created in order to give UPN and WB stations, not mentioned as becoming CW affiliates, another option besides becoming independent in addition to competing against The CW. It was announced on April 24 that WTLH would create a new second digital subchannel to become Tallahassee's CW affiliate. These plans were later modified in August to make WFXU/WTLF the primary CW affiliate with a simulcast provided on WTLH-DT2. This arrangement took effect when the network premiered on September 18 while, back on September 5, WCTV's UPN subchannel joined MyNetworkTV. The Pegasus station group was sold in August 2006 to private investment firm CP Media, LLC of Wilkes-Barre, Pennsylvania for $55.5 million. Eventually, CP Media formed a new media company, New Age Media. Around this time, KB Prime Media sold WTLF to Mystic Broadcast Group which in turn promptly sold it to MPS Media. Meanwhile, WFXU was eventually sold to Budd Broadcasting and became a separate outlet leaving WTLF and WTLH-DT2 as Tallahassee's CW affiliate. On September 25, 2013, New Age Media announced that it would sell most of its stations to the Sinclair Broadcast Group. In order to comply with FCC ownership restrictions, since Sinclair already owns WTWC, its partner company Cunningham Broadcasting planned to acquire the WTLH license but Sinclair was slated to operate the station through shared services agreements. On October 31, 2014, New Age Media requested the dismissal of its application to sell WTLH; the next day, Sinclair purchased the non-license assets of WTLF and WTLH and began operating them through a master service agreement. At some point after the transaction occurred, Sinclair moved WTLH's Fox affiliation to WTWC's second subchannel. At that point, MeTV programming moved from WTLH's third digital subchannel to its main channel; the simulcast of WTLF continues on that outlet's second subchannel.
