I have some contacts in the broadcast industry and they told me a local affiliate can exercise their right to be the sole NBC, CBS, or ABC network in the area. Im guessing stations didn't mind other affiliates in the area until things got so competitive. It's sad really because WCYB has long been the channel we watched for high school sports back in the day. I think WJHL (Johnson City) and WDBJ (Roanoke) have been taken off the air in SWVA as well, haven't they?
