It is getting so close in the USA to have regular analog tv signals to become digital in February 2009. Make sure to have all tv sets changed over, or you will not be able to see anything. Most tv sets sold before 2007 are NOT digital ready! You will need a converter box to see anything digital. Double check all your tv sets in your house for anything made before 2007, and get your set ready for the change. Most of the analog signals are to be used by local governments, colleges, and companies for other usages.
