Washington ? The Senate on Monday voted unanimously to postpone the upcoming transition from analog to digital television broadcasting by four months to June 12 — setting the stage for Congress to pass the proposal as early as today.

Monday’s Senate vote is a big victory for the Obama administration and Democrats in Congress, who have been pushing for a delay amid growing concerns that too many Americans won’t be ready for the currently scheduled Feb. 17 changeover.

The Nielsen Co. estimates that more than 6.5 million U.S. households that rely on analog television sets to pick up over-the-air broadcast signals could see their TV sets go dark next month if the transition is not postponed.

The issue now goes to the House, where Commerce Committee Chairman Henry Waxman, D-Calif., has vowed to work with House leaders to bring Rockefeller’s bill up for a floor vote on Tuesday.
