In its final update before the June 12 deadline for converting all full-powered U.S. television stations to digital transmission, The Nielsen Co. reported that 2.8 million American households, or 2.5 percent of the television market, are completely unready for the transition.

Younger, African American and Hispanic homes are disproportionately unready, while the elderly are the most ready.

“Since February, when the U.S. government postponed the transition for three months, the number of households that are completely unready has been cut in half – from 5.8 million to 2.8 million homes,” said Sara Erichson, president of media client services for Nielsen.

“Given the importance that television plays in the day-to-day life of most people, we expect that most of the remaining unready homes will take the necessary steps to get ready once the stations make the final switch to digital transmission.”
