You can now apply for the $40.00 coupons to get a digital to analog converter to use on analog television sets connected to an antenna. Analog television is going away in February 2009 so if you have tvs that are not connected to cable or satellite, you need to get one in order to continue to use the tv.

You can apply either online or by telephone.
I successfully applied for one myself online.
