A console war is competition for dominance in market share in video game consoles. The main competition is in home video game consoles and handheld game consoles markets, although there are also microconsoles and dedicated consoles. Console wars do not necessarily have a clear winner in each case, but the outcome may determine whether a console manufacturer remains a part of the video game industry.
In seventh generation era of video game consoles alone, there were three major home video game consoles competing each another: PlayStation 3 by Sony, Xbox 360 by Microsoft and Wii by Nintendo. Sony and Nintendo also compete in the handheld game console market at the same time, with their handhelds PlayStation Portable and Nintendo DS respectively. With the advance of eighth generation of video game consoles, the three companies continued to compete for dominance in market share with their successor video game consoles, PlayStation 4 by Sony, Xbox One by Microsoft and Wii U by Nintendo in home video game console market and PlayStation Vita by Sony and Nintendo 3DS by Nintendo in handheld game console market. Sega was once also a significant manufacturer, but now becomes a third-party video game publisher.
In Hyperdimension Neptunia
In the Hyperdimension Neptunia game series, the world of Gamindustri (ゲイムギョウ界 Geimugyō-kai?, a pun on ゲーム業界 Gēmu gyōkai, "game industry") is divided into four regions: Planeptune, Lastation, Lowee, and Leanbox. Each region is completely different from the others in appearance and atmosphere, with each representing a specific video game console (Sega Neptune, Sony PlayStation, Nintendo Wii and Microsoft Xbox respectively). The four goddesses, one for each region, also known as the Console Patron Units (or simply CPU) are fighting each another for "shares" (the amount of influence a CPU and her nation has over a certain place). The war is also known as the "Console War", resembling the real-world competitions for dominance in market share in the video game console marketplace. In the story of the game the Console War had lasted for thousands of years, which is one of the main driving plot lines in the series.
