After the closedown of the original G4, SLN! Media Group decided to revive it. In April 2017, Lava Lamp Entertainment and Laserium-GBC Networks officially acquired G4 and G4 Movies, in exchange for minor assets.
On July 23, 2020, G4 was abruptly shutdown with little notice. A day later, a G4 revival was announced during Comic-Con@Home.
