Washington, DC -- Beginning Jan. 1, the estimated 13-21 million U.S. households that rely on antennas to receive analog TV signals will be able to ask the government for two $40 coupons toward the purchase of digital converters, the Associated Press reported. The converters will be needed to view digital TV signals once analog broadcasts are discontinued in 2009. Congress has allotted $1.5 billion for the program, with converters from DigitalSTREAM, Zenith, Magnavox and Philco already having been certified. The converters will be sold at retailers including Best Buy, Wal-Mart, Target, Kmart and RadioShack. Those interested in the coupon program can apply at DTV2009.gov, which will go live on Jan. 1.
