Plans forcing US broadcasters to switch analogue television signals off by 2009 has been agreed by Congress.

The legislation fixes a deadline of 17 February 2009 for the switch-off and secures $1.5bn (£844m) for ensuring Americans are digital-ready. Each family is entitled to $80 (£45) towards a set-top box under the new programme.

Republican and digital-advocate Joe Barton called the move a "great technical revolution."

The bill was passed before in December but Senate technical changes meant confirmation was necessary.
