Because so many don’t seem to realize the facts about television switching from analog to digital signalas in the United States here is a site of interest for information. The U.S. Department of Commerce’s TV Converter Box Program So no need to rush and throw out your older televisions if they lack a digital tuner.
Personally, I think the government kept the whole thing relatively quiet until recently so people will just assume that they need to buy new televisions in some twisted idea that it’ll somehow help the economy or something. That or they’ve under funded the program like they are wont to do when they change public policy but want the public to pay for the change. It’s been done before and will be done again.
