Came on the air in 1985 as an independent with the slogan, "We're Taking You To The Top!" according to Wikipedia.  The channel didn't take Fox affiliation until 1990, but did air some Fox-carried specials from time to time.  At one time was an affiliate of the now-defunct PTEN - Prime Time Entertainment Network, a short-lived "fifth network" in the mid 90's.   After launching Huntsville's second digital broadcast, the station added then cable-only "WAWB-TV" to the digital subchannel for non-cable viewers.  This is now My Network TV and sloganed as "WAMY-TV".  WZDX was co-located with WAAY on a tower that collapsed in 2003, killing three workers.
This station elected to keep analog broadcasts on until the new June 12th deadline.
In July 2009 it was announced that this station would be picking up the ESPN-created "SEC Network" for collegiate sporting events.  In June 2011 the station upgraded from its previous 200 kW of power to 700 kW.  The station's -.2 subchannel carries the Huntsville market's My Network TV affiliation, and the -.3 has the retro-television themed MeTV network.  In August 2016 it was discovered that several sites are claiming MeTV will be replaced with Laff at some point in the future.  In late August 2016 the station added a fourth subchannel featuring Escape TV, part of a deal between Katz Broadcasting the station's owners, Nexstar Broadcasting. 

At the end of July 2017 the station received a permit to relocate from RF channel 41 to 18 as part of the FCC repacking process.
