Mean Machines, a long-standing British games magazine, split into two separate magazines, focusing on the two then-major video games console companies: Sega and Nintendo. The Sega-based magazine retained the original title, Mean Machines Sega, while the Nintendo magazine was named Nintendo Magazine System (NMS).
The first issue of Nintendo Magazine System was released on 1 October 1992. Its name was later changed to Nintendo Magazine, Nintendo Official Magazine (NOM) then Nintendo Official Magazine UK, before its publisher was changed from EMAP to Future plc. After this change, the magazine was renamed to its current name, Official Nintendo Magazine (ONM), and received a new set of staff. Its numbering was also reset. It reached its 50th issue on 20 November 2009 and its 100th issue in October 2013.
In March 2011, the UK magazine underwent a change in the style and layout of the contents in the magazine, while adding new features. The first issue released in this format featured a "3D without glasses" cover for the launch of Nintendo 3DS.
A new version was introduced in November 2012, with the release of the Wii U.
