question: The beginnings of digital television allowed what affiliate in Wheeling, West Virginia to begin airing ABC programs digitally?
sentence: Still, ABC's limited reach would continue to hobble it for the next two decades; several smaller markets would not grow large enough to support a full-time ABC affiliate until the 1960s, with some very small markets having to wait as late as the 1980s or even the advent of digital television in the 2000s, which allowed stations like WTRF-TV in Wheeling, West Virginia to begin airing ABC programming on a digital subchannel after airing the network's programs outside of recommended timeslots decades before.
