In September 1998, WTXL established a cable-only affiliate of The WB. Known as "WBXT" and originally on-air as "WB 28" (based on the cable channel location), it was part of the national WB 100+ service. Since it was available exclusively on cable, the call sign was fictional in nature and thus not officially recognized by the FCC. WTXL provided local advertisements and performed promotional duties for "WBXT". On April 1, 2005, UPN affiliates WFXU/WTLF switched to The WB through The WB 100+. UPN promptly signed with WCTV which launched a new second digital subchannel to carry the network. As a result, the "WBXT" operation was shut down.
