The government program that provides $40 coupons for digital TV converter boxes is winding down.

Friday will be the last day it accepts requests.

Full-power U.S. TV stations turned off their analog broadcasts on June 12. Households that still need the boxes to get digital signals to their TVs can order a coupon at http://www.dtv2009.gov or by calling 1-888-DTV-2009.

Each household can request two coupons.

As of Wednesday, the government had sent out 63.4 million coupons, of which 33.8 million had been redeemed at a cost of $1.3 billion.

Government data show that there’s still demand for coupons. On Tuesday, 49,000 were requested.
