NBC’s biggest local affiliate groups have decided against airing the network’s upcoming 30 Rock reunion special, and that means at least half of the country won’t even have the opportunity to watch it when it airs on the network on Thursday night. According to Vulture, huge TV-station groups like Hearst, Sinclair Broadcast Group, Gray Television, Nexstar, and Tegna have all told NBC that they will be preempting the hour-long special.
