The HoloNet, also spelled Holonet, was a large communications system used by the citizens of the Galactic Republic and its successor state, the Galactic Empire. The HoloNet News was broadcast on the HoloNet during the reign of both governments. Following the Battle of Endor, the New Republic, the successor government created by the Rebel Alliance, took control of HoloNet and began easing the Imperial restrictions and censorship.

HoloNet programming could be watched via a holocaster. The Holonet could also be used to look up information. C-3PO connected to the Holonet to learn that the moon Kef Bir used to be entirely underwater and recent information on how terrible the Battle of Endor was.

During the Clone Wars, the Galactic Republic used HoloNet to broadcast news and information to the general public. While serving as CountDooku‘s Sith apprentice, the Jedi MasterQuinlan Vos earned the nickname «Admiral Enigma» on the Republic’s HoloNet.
