Milwaukee's WISN had previously requested Time Warner Cable/Racine drop Chicago's WLS from their lineup, so that they could be the exclusive ABC affiliate for the area. (Racine is part of the Milwaukee DMA.) Now, they are requiring TWC to black out any programming, be it ABC network programming or syndicated shows, on WLS that WISN also carries.
