This episode, along with "Heroes" and "Splicer" were released on VHS as Batman Beyond: Tech Wars. It was later paired up with the VHS release of Batman Beyond: Disappearing Inque (consisting of "Black Out", "Disappearing Inque" and "Shriek") on DVD.
The newscaster in the opening scene (set 35 years before Batman Beyond) looks a lot like Summer Gleason from Batman: The Animated Series. Assuming that Bruce is 75-80 in Beyond, and was 35-40 in TAS, then that would set the intro scene about 5-10 years after TAS, so it could well be Summer.
