A bill that would have delayed the February 17 switchover from analog to digital television failed to get the necessary two-thirds vote in the House Wednesday after House Republicans united to block it. The GOP members had argued that a delay would place undue hardship on smaller broadcasters who would be forced to maintain dual transmitter sites for an additional 90 days and that it would confuse consumers. They favor a more limited measure that would free up funds to allow more $40 vouchers for converter boxes to be sent to those requesting them. The National Telecommunications and Information Administration says that 2.6 million coupon requests are currently wait-listed.
