 The station changed its call letters to WWAZ in late 2004, in anticipation for a change in affiliation to the Spanish-language Azteca América network; however the station never did join Azteca and Pappas ended up dropping almost all of its affiliations with the network from its stations in July 2007 during a conflict with the network, replacing it with its own new Spanish-language service, TuVision.During TuVision's life, the network was never carried by WWAZ.Most of the station's audience prior to 2007 received its signal over-the-air, as WWAZ and Pappas had previously not pursued any must-carry provisions with local cable and national satellite providers because of affiliation uncertainties; for instance, the station was not carried on the Charter Communications system in Fond du Lac.
