Home video game systems, also known as consoles, are a popular form of entertainment. In 2000, Sony estimated that one out of every four households in the United States had a Sony PlayStation. Since then the numbers have only increased, with systems like the Nintendo Wii luring the Holy Grail of the video game market: the casual gamer.

In this article you will learn what video game systems are, a little about the history of game consoles, what is inside a game console and what the future holds for these systems. You will also learn a little about the games these systems play.
Let's start with the most basic question: What exactly is a video game console?
At its core, a video game system is a highly specialized computer. In fact, most systems are based on the same central processing units (CPUs) used in many desktop computers. To keep the cost of the video game system within reasonable limits, most manufacturers use a CPU that has been widely available for long enough to undergo a significant decrease in cost.
Why would people buy a game console instead of a computer? There are several reasons:
- A video game console is less expensive than a tricked-out computer designed to run video games. Current generation consoles cost between $200 to $500, whereas a fully-loaded gaming computer can cost more than $4,000.
- There's no long wait for the game to load.
- Video game systems are designed to be part of your entertainment system. This means that they are easy to connect to your TV and stereo.
- There are no compatibility issues, such as operating system, DirectX drivers, correct audio card, supported game controller, resolution and so on.
- Game developers know exactly what components are in each system, so games are written to take full advantage of the hardware.
- The degree of technical knowledge required to set up and use it is much lower. Most game consoles are truly "plug and play."
- Most video game systems have games that allow multiple players. This is a difficult process with a typical home computer.
A Short HistoryVideo games have been around since the early 1970s. The first commercial arcade video game, Computer Space by Nutting Associates, was introduced in 1971. In 1972, Atari introduced Pong to the arcades. An interesting item to note is that Atari was formed by Nolan Bushnell, the man who developed Computer Space. He left Nutting Associates to found Atari, which then produced Pong, the first truly successful commercial arcade video game.
Pong was a great hit when it came out. Move your cursor to get the slides to bounce back the moving square -- it will speed up as you That same year, Magnavox offered the first home video game system. Dubbed the Odyssey, it did not even have a microprocessor! The core of the system was a board with about four-dozen transistors and diodes. The Odyssey was very limited -- it could only produce very simple graphics, and required that custom plastic overlays be taped over the television screen. In 1975, Atari introduced a home version of its popular arcade game, Pong. The original home version of Pong was sold exclusively through Sears, and even carried the Sears logo. Pong was a phenomenal success, opening the door to the future of home video games.
The Atari 2600
The hardware in the 2600 was quite sophisticated at the time, although it seems incredibly simple now. It consisted of:
- MOS 6502 microprocessor
- Stella, a custom graphics chip that controlled the synchronization to the TV and all other video processing tasks
- 128 bytes of RAM
- 4-kilobyte ROM-based game cartridges
The NES introduced three very important concepts to the video game system industry:
- Using a pad controller instead of a joystick
- Creating authentic reproductions of arcade video games for the home system
- Using the hardware as a loss leader by aggressively pricing it, then making a profit on the games themselves
Nintendo continued to develop and introduce new game consoles. Other companies, such as Sega and Sony, created their own home video game systems. Let's look at the core parts of any current video game system.
Game System BasicsThe basic pieces really haven't changed that much since the birth of the Atari 2600. Here's a list of the core components that all video game systems have in common:
- User control interface
- Software kernel
- Storage medium for games
- Video output
- Audio output
- Power supply
Ever since the early days of the 2600, video game systems have relied on RAM to provide temporary storage of games as they're being played. Without RAM, even the fastest CPU could not provide the necessary speed for an interactive gaming experience.
The software kernel is the console's operating system. It provides the interface between the various pieces of hardware, allowing the video game programmers to write code using common software libraries and tools.
The two most common storage technologies used for video games today are CD and ROM-based cartridges. Current systems also offer some type of solid-state memory cards for storing saved games and personal information. Systems like the PlayStation 2, have DVD drives. The PlayStation 3 goes even further -- it has a Blu-Ray DVD drive.
All game consoles provide a video signal that is compatible with television. Depending on your country, this may be NTSC, PAL or possibly even SECAM. Most consoles have a dedicated graphics processor that provides specialized mapping, texturing and geometric functions, in addition to controlling video output. Another dedicated chip typically handles the audio processing chores and outputs stereo sound or, in some cases, digital surround sound!
The GamesThe software used on these dedicated computer systems has evolved amazingly from the simple rectangular blips used in Pong. Games today feature richly textured, full-color graphics, awesome sound and complex interaction between player and system. The increased storage capacity of the cartridges and discs allows game developers to include incredibly detailed graphics and CD-quality soundtracks. Several of the video game systems have built-in special effects that add features like unique lighting or texture mapping in real-time.
There is a huge variety of games available. Here are just a few of the games you can play on the most popular consoles:
Metal Gear Solid 4
Grand Theft Auto IV
FIFA Soccer 08
Marvel Ultimate Alliance
Call of Duty 4
LEGO Star Wars II
Guitar Hero III
Mario Kart Wii
Super Mario Galaxy
