Eight broadcasters will start a joint million-dollar promotion to publicize the December launch of digital satellite operations during the traditional Obon holidays beginning this Thursday.

The 15-second commercial, produced by NHK, five commercial terrestrial networks, the Wowow analog satcaster and movie web Star Channel, will be aired by all eight broadcasters on their terrestrial programs through Aug. 16.

The rival broadcasters agreed to the unusual joint promo in an attempt to raise public awareness of the December launch of digital satellite broadcasting by the eight.

Each will add its own three-second promo at the end of the 15-second commercial.
