A recent poll of TV watchers shows that many Americans aren't aware the end times are coming for analog broadcast signals. "The survey found that the group most affected by the analog cutoff -- those with no cable or satellite service -- are most in the dark about what will happen to their sets: Only one-third of them had heard that their TVs are set to stop receiving programs. Of course, there are solutions. Congress is subsidizing the purchase of digital television receivers. And the cable TV industry is hoping that this will spur the last holdouts to buy pay TV."
