WBXX began operation in October 6, 1997; the station is the only one that was ever built by ACME Communications from the ground up (KWBQ in Albuquerque, New Mexico was also signed on by ACME but its construction permit originally belonged to another entity).
WBXX is the only full-powered Knoxville-market station to be licensed in a city in the Central Time Zone; Cumberland County (where Crossville is located) and Fentress County are the only two counties in the Knoxville market that observe Central Time, one hour earlier than Knoxville, in Eastern Time.
