Today's The Day - Sources (and One Answer)
Going through my visitor logs (biggest day yet, as you can imagine), I find the most common search query leading people here is "what time is this happening?". The simple answer is that it varies by station, and some have undoubtably happened already. From what I've seen, there should be a lot of turnoffs around lunchtime, dinnertime and finally at 11:59 tonight. There's been a certain amount of confusion as to what all the coverage referencing "midnight" referred to. It's the one that comes between Friday and Saturday, not Thursday and Friday.
There are two places I would keep checking today and over the next few days. One is the AVS Forum transition thread [now LOCKED, see update below] I mentioned in my last post. I expect that people will be contributing local reactions from all over the country there. Another is the AVS Forum "OTA" (for Over The Air) thread for your area (not all areas have one). Go to the thread index to have a look (if there's no "OTA" thread for your area, check the "HDTV" thread instead).
That's all for the moment!
UPDATE: The AVS transition thread mentioned above has been LOCKED. Two new threads have been started for news starting today - Stories of the DTV Transition for first-person accounts and A Day of Reckoning for general discussion. Check them out!
