Also Worth a Look: What is the Digital TV Deadline?

The FCC currently has a February 17, 2009, deadline for the transition to all digital broadcasting.
On this date, all analog broadcasting will stop, and consumers will need to buy converter boxes to receive programming on their older TVs.

TV stations must have the equipment to send digital broadcasts, and consumers must have the TVs to receive them.
