With the transition to digital television less than two weeks away, America’s broadcasters are actively engaged in a major on-air campaign signaling to viewers the impending June 12 deadline.

Full-power television stations that have yet to switch to digital have begun airing a new series of television spots counting down the final three weeks until the transition. Produced by NAB, each spot is 15 seconds in length and marks the remaining three weeks, two weeks, seven days, six days, five days, four days, three days, two days and less than 24 hours from the deadline. The two-week countdown spot can be viewed here.

The series is aimed at alerting viewers to the nearing deadline and urging them to upgrade their TV sets in advance. As part of the final push, NAB has also distributed to stations an updated half-hour educational program covering the basics of the transition to digital television (DTV), which stations are required to air at least once before June 12. Eligible broadcast stations may also run NAB’s instructional DTV “Nightlight” video, which will serve as the only analog programming in certain markets after the transition is completed. Both videos are available in English and Spanish.

“America’s broadcasters are pulling out all the stops during these final weeks to ensure viewers are ready for the June 12 deadline,” said NAB Vice President of DTV Transition Jonathan Collegio. “This critical on-air campaign culminates our industry’s billion-dollar education effort to educate consumers about this historic switch.”
