Sales clerks at a number of TV retailers in Massachusetts gave inaccurate information regarding the upcoming analog-to-digital television conversion. Imagine that: Sales clerks giving inaccurate information! The switch will require users of older televisions to purchase a basic set-top box partially subsidized by the government, but does not require viewers to buy a new TV. Eric Bourassa, a consumer advocate with MassPIRG, which commissioned the study, says "retailers should do a better job training their staff so that going forward, consumers that go into the stores can get the right information."
