Holofeeds were a type of holographic technology. By the Galactic Civil War, they could be used to show images to display to many individuals, such as Diadem Square.
Holofeed programs, such as news and interview programs, could be broadcast to large areas of a planet. The holofeed program on the planet Kwenn with the largest regular audience was called Remember Kwenn, and was hosted by the Troig Reezingrom Abbayav.
