The emerging Asian markets and mobile games on smartphones in particular are driving the growth of the industry.
As of 2015, video games generated sales of USD 74 billion annually worldwide, and were the third-largest segment in the U. entertainment market, behind broadcast and cable TV.
While most arcade games are housed in a vertical cabinet, which the user typically stands in front of to play, some arcade games use a tabletop approach, in which the display screen is housed in a table-style cabinet with a see-through table top.
In addition to personal computers, there are other devices which have the ability to play games but are not dedicated video game machines, such as smartphones, PDAs and graphing calculators.
In common use a "PC game" refers to a form of media that involves a player interacting with a personal computer connected to a video monitor.
These platforms range from large mainframe computers to small handheld computing devices.
Specialized video games such as arcade games, in which the video game components are housed in a large, typically coin-operated chassis, while common in the 1980s in video arcades, have gradually declined due to the widespread availability of affordable home video game consoles (e.g., Play Station 4, Xbox One and Nintendo Switch) and video games on desktop and laptop computers and smartphones.
The input device used for games, the game controller, varies across platforms.
