I am pretty sure there is no graphic that says that on the screen, if I remember correctly. I think James just says that out of habit for station identification. If I recall he usually says "This is WCFT Tuscaloosa, WJSU Anniston, WBMA Birmingham." Probably just no one has caught it to remind him to change it.
Kind of like Birmingham and ABC. A top 50 market with full power ABC on three subchannels. Although I suppose they do get even better coverage than they did before, and technically the LD station is the affiliate.
I always have wondered why they didn't take WTTO 21 and make it ABC on 21.1 and brand as ABC 21. I suppose they have their reasons.
