The HoloNet of the New Republic functioned as a secondary method of communication for both the Rebel Alliance and later, the New Republic, during their conflict against the forces of the Galactic Empire.
The NR HoloNet's operations began as early as 4 ABY, and it was responsible for broadcasting news of the defeat of the Death Star II to all HoloNet receivers located on Coruscant, which subsequently triggered the Coruscant Uprising on that planet.
Following the New Republic's rise to power on Coruscant in 7 ABY, it remained their primary broadcasting system. It was around this period that Gara Petothel, an Imperial agent, attempted to send an encrypted message through the HoloNet, hoping it would be received by the warlord Zsinj.
