In case you’ve managed to miss the news, tonight at midnight will mark the original DTV transition date, when full power over-the-air broadcast stations were supposed to shut off their analog signal and just broadcast in digital. According to the FCC, 421 stations will do so tonight. Since 220 stations have already made the switch, that means 641 stations – or 36% – will have met the original deadline, even though the date has been extended to June 12.
