As of June 12, 2009, at some point in the day, all broadcast analog TV stations are to stop programming in analog and exclusively go digital. This is what you see in the Boston area the day after (6/1
...
3/09). Some stations may be required to stay on a week or so longer to show an instructional video on how to convert over to the digital format. In this case, channels 4 (WBZ) and 5 (WCVB) are sticking around for the instructional video. The video is about 20 minutes long, half in English, and the other half in Spanish, but it's the exact same thing.
This doesnot affect most poeple, since most have cable, sattelite, or telcom, and those who do use antennas (like myself), likely have a digital television, or have got a converter box.
Of course, my TV is capable of digital reception, but went down the dial to see what's still alive in analog-land.
NOTE: If you'd like to try this at home, and you enter an analog station, and the digital one pops up instead, make sure you had analog stations programmed in to begin with, and end your channel selection with ".0", or "-0", depending on the TV. I did this a couple times here, so no example is needed.
In a mater of a week or two, all analog TV will no longer exist, except for the low-power stations (college campuses, and the like).
Make sure your TV, is DTV. :)
