The story
Nextmedia was founded in 2007 by acquiring the publishing assets of four companies:
Horwitz Publications (founded 1960)
Next Publishing (founded 1987)
Chevron Publishing Group (founded 1988)
Bluewater Publishing (founded 2006)
In 2013, Nextmedia itself was acquired by the Forum Media Group. Shortly thereafter, Nextmedia acquired the assets of Haymarket Media Pty Ltd.
In 2018, consumer computing and tech assets (including Atomic, Hyper, PC PowerPlay, and PC Tech & Authority) were sold to Future plc. Future subsequently acquired more consumer titles of Nextmedia including Australian Camera, Australian Guitar, Australian Hi-Fi, ProPhoto, and Sound+Image.
