Video game industry

The video game industry is the industry involved in the development, marketing, and monetization of video games. It encompasses dozens of job disciplines and its component parts employ thousands of people worldwide.

The video game industry has grown from focused markets to mainstream in the recent years. As of 2018, July, video games generated sales of US$134.9 billion annually worldwide. In the US, it took in about US$ 9.5 billion in 2007, 11.7 billion in 2008, and 25.1 billion in 2010, according to the ESA annual report.

Modern personal computers owe many advances and innovations to the game industry: sound cards, graphics cards and 3D graphic accelerators, faster CPUs, and dedicated co-processors like PhysX are a few of the more notable improvements. Sound cards, for example, were originally developed for an addition of digital-quality sound to games and only later were they improved for the music industry.[citation needed] Graphics cards were originally developed to provide more screen colors; and later on to support graphical user interfaces (GUIs) and games. This drove the need for higher resolutions and 3D acceleration.
