For those television stations that did not end analog broadcasting on Feb. 17, 2009, the FCC has set up the criteria under which stations may elect to continue their analog signals until the end of the extension period on June 12, 2009, or elect a date sooner than that if they desire.
On March 17, 2009 stations have to notify the FCC of their intentions of when they will cease analog broadcasts. This will be a binding notice, and cannot be changed once the election has been made by the station, unless there is a catastrophic transmitter or equipment failure or a natural disaster of some sort.
