Digital Television a Surprise?

I’m astonished at what I’m hearing today, one day after analog television broadcasting stopped in the United States. There are people who managed to be surprised by this? How???? If you watch television at all, you must have seen or heard an announcement sometime in the last several months, after the last try at switching to digital broadcasts. I absolutely can’t comprehend how hundreds of thousands of people could be taken unaware, and they’re calling the television stations to ask what’s wrong with their signal!
