I just noticed, as evidenced by the screenshot of my local affiliate, KFTR 46-6 in L.A., that I’ve attached to this post, that Digi-TV has ceased operations. According to the subchannel network’s Wikipedia page, it launched in September of last year and shut down today, August 1. So after less than a year, Digi-TV is the newest addition to the graveyard of defunct TV networks, whether primary or subchannel.
