The Grand Army of the Republic broadcast was a holographic music broadcast hosted by a BD-3000 luxury droid Hologram VJ, dedicated to the servicemen of the Grand Army of the Republic during the Clone Wars. The clone troopers at Rishi Station occasionally played this broadcast, due to the dull nature of the remote posting.
The Grand Army of the Republic broadcast first appeared in "Rookies," the fifth episode of Star Wars: The Clone Wars, which premiered in 2008.
