The previous history of The WB in Charleston saw that network being carried exclusively on cable through "WBLN", an affiliate of The WB's smaller-market The WB 100+ Station Group and run by Coastal Media & Broadcasting and Cox Communications from September 21, 1998 until the network's end in September 2006, and was located on channel 14 on most cable systems. Before WBLN's launch, the network originated on both WGN's national feed and WCTP (the current-day WCIV) in January 1995, which changed their calls to WBNU to fit their new affiliation. In January 1997, WBNU signed an affiliation agreement with UPN and changed their calls to WMMP after a change in ownership, staying with that network until September 2006 when they affiliated with MyNetworkTV; the short gap in 1997 saw viewers receive WB programming only from Superstation WGN before WBLN and the WB 100+ system launched.
