Simplicity is achieved in part through the use of game cartridges or other simplified methods of distribution, easing the effort of launching a game. However, this leads to ubiquitous proprietary formats that creates competition for market share. More recent consoles have shown further confluence with home computers, making it easy for developers to release games on multiple platforms. Further, modern consoles can serve as replacements for media players with capabilities to play films and music from optical media or streaming media services. Video game consoles are usually sold on a 5-7 year cycle called a generation, with consoles made with similar technical capabilities or made around the same time period grouped into one generation. The industry has developed a razor and blades model: manufacturers often sell consoles at low prices, sometimes at a loss, while primarily making a profit from the licensing fees for each game sold. Planned obsolescence then draws consumers into buying the next console generation. While numerous manufacturers have come and gone in the history of the console market, there have always been two or three dominant leaders in the market, with the current market led by

History

The first video game consoles were produced in the early 1970s. Ralph H. Baer devised the concept of playing simple, spot-based games on a television screen in 1966, which later became the basis of the Magnavox Odyssey in 1972. Inspired by the table tennis game on the Odyssey, Nolan Bushnell,

Programmable consoles using swappable ROM cartridges were introduced with the Fairchild Channel F in 1976, though popularized with the Atari 2600 released in 1977. Handheld consoles emerged from technology improvements in handheld electronic games as these shifted from mechanical to electronic/digital logic, and away from

in 1989. Both home and handheld consoles have become more advanced following global changes in technology. These technological shifts include including improved electronic and computer chip manufacturing to increase computational power at lower costs and size, the introduction of 3D graphics and hardware-based graphic processors for real-time rendering, digital communications such as the Internet, wireless networking and Bluetooth, and larger and denser media formats as well as digital distribution. Following the same type of Moore's law progression, home consoles are grouped into generations, each lasting approximately five years. Consoles within each generation share similar specifications and features, such as processor word size. While no one grouping of consoles by generation is universally accepted, one breakdown of generations, showing representative consoles, of each is shown below.


Types

Most consoles are considered programmable consoles and have the means for the player to switch between different games. Traditionally, this has been done by switching a physical game cartridge or game card or through using optical media. It is now common to download games through digital distribution and store them on internal or external digital storage devices. Dedicated consoles were very popular in the first generation until they were gradually replaced by second generation that use ROM cartridges. The fourth generation gradually merged to optical media. It is now common to download games through digital distribution and store them on internal or external digital storage devices. Some consoles are considered dedicated consoles, in which

s available for the console are "baked" onto the hardware, either by being programmed via the circuitry or set in the read-only flash memory of the console. Thus, the console's game library cannot be added to or changed directly by the user. The user can typically switch between games on dedicated consoles using hardware switches on the console, or through in-game menus. Dedicated consoles were common in the first generation of home consoles, such as the Magnavox Odyssey and the home console version of ''Pong'', and more recently have been used for retro-consoles such as the NES Classic Edition and Sega Genesis Mini.


Home video game console

Home video game consoles are meant to be connected to a television or other type of monitor, with power supplied through an outlet. This requires the unit to be used in a fixed location, typically at home in one's living room. Separate game controllers, connected through wired or wireless connections, are used to provide input to the game. Early examples include the Atari 2600, the Nintendo Entertainment System, and the Sega Genesis; newer examples include the

Plug and play/Retro consoles

During the later part of video game history, there have been specialized consoles using computing components to offer multiple older games to players. Most of these plug directly into one's television, and thus are often called plug-and-play consoles. They are also considered dedicated consoles since it is generally impossible to access the computing components by an average consumer, though tech-savvy consumers often have found ways to

became more practical with the higher density of transistors per chip, but to address the correct blocks of memory, processors needed to be updated to use larger word sizes and allot for larger bandwidth in chip communications. All these improvements did increase the cost of manufacturing but at a rate far less than the gains in overall processing power, which helped to make home computers and consoles inexpensive for the consumer, all related to Moore's law of technological improvements. For the consoles of the 1980s to 1990s, these improvements were evident in the marketing in the late 1980s to 1990s during the "bit wars", where console manufacturers had focused on their console's processor's word size as a selling point. Consoles since the 2000s are more similar to personal computers, building in memory, storage features, and networking capabilities to avoid the limitations of the past. The confluence with personal computers eased software development for both computer and console games, allowing developers to target both platforms. However, consoles differ from computers as most of the hardware components are preselected and customized between the console manufacturer and hardware component provider to assure a consistent performance target for developers. Whereas personal computer motherboards are designed with the needs for allowing consumers to add their desired selection of hardware components, the fixed set of hardware for consoles enables console manufacturers to optimize the size and design of the motherboard and hardware, often integrating key hardware components into the motherboard circuitry itself. Often, multiple components such as the central processing unit and graphics processing unit can be combined into a single chip, otherwise known as a

(SoC), which is a further reduction in size and cost. In addition, consoles tend to focus on components that give the unit high game performance such as the CPU and GPU, and as a tradeoff to keep their prices in expected ranges, use less memory and storage space compared to typical personal computers. In comparison to the early years of the industry, where most consoles were made directly by the company selling the console, many consoles of today are generally constructed through a

. The instruction set defines low-level machine code to be sent to the CPU to achieve specific results on the chip. Differences in the instruction set architecture of CPU of consoles of a given generation can make for difficulty in software portability. This had been used by manufacturers to keep software titles exclusive to their platform as one means to compete with others. Consoles prior to the sixth generation typically used chips that the hardware and software developers were most familiar with, but as personal computers stabilized on the x86 architecture, console manufacturers followed suit as to help easily port games between computer and console. :Newer CPUs may also feature multiple processing cores, which are also identified in their specification.

Modern console GPUs can be run at a different frequency from the CPU, even at variable frequencies to increases its processing power at the cost of higher energy draw. The performance of GPUs in consoles can be estimated through

This is data that must be transferred to and from the CPU and GPU quickly as needed without requiring these chips to need high memory caches themselves. ;Internal storage :Newer consoles have included internal storage devices, such as

Some consoles power supplies are built into the unit, so that the consumer plugs the unit directly to a wall socket, but more often, the console ships with an AC adapter, colloquially known as a "power brick", that converts the power outside of the unit. On handheld units the power supply will either be from a battery compartment, or optionally from a direct power connection from an AC adapter, or from a rechargeable battery pack built into the unit. ;Cooling systems :More advanced computing systems generate heat, and require active cooling systems to keep the hardware at safe operating temperatures.

Controller connections are typically offered on the front of the console, while power and most other connections are usually found on the back to keep cables out of the way.


Controllers

All game consoles require player input through a game controller to provide a method to move the player character in a specific direction and a variation of buttons to perform other in-game actions such as jumping or interacting with the game world. Though controllers have become more featured over the years, they still provide less control over a game compared to personal computers or mobile gaming. The type of controller available to a game can fundamentally change the style of how a console game will or can be played. However, this has also inspired changes in game design to create games that accommodate for the comparatively limited controls available on consoles. Controllers have come in a variety of styles over the history of consoles. Some common types include: ; Paddle :A unit with a single knob or dial and usually one or two buttons. Turning the knob typically allows one to move an on-screen object along one axis (such as the paddle in a table tennis game), while the buttons can have additional features. ;
Joystick A joystick, sometimes called a flight stick, is an input device consisting of a stick that pivots on a base and reports its angle or direction to the device it is controlling. A joystick, also known as the control column, is the principal cont ...
:A unit that has a long handle that can pivot freely along multiple directions along with one or more buttons. The unit senses the direction that the joystick is pushed, allowing for simultaneous movement in two directions within a game. ; Gamepad :A unit that contains a variety of buttons, triggers, and directional controls - either D-pads or analog sticks or both.

Controllers are nominally built into a handheld unit, though some newer ones allow for separate wireless controllers to also be used.


Game media

While the first game consoles were dedicated game systems, with the games programmed into the console's hardware, the Fairchild Channel F introduced the ability to store games in a form separate from the console's internal circuitry, thus allowing the consumer to purchase new games to play on the system. Since the Channel F, nearly all game consoles have featured the ability to purchase and swap games through some form, through those forms have changes with improvements in technology. ; ROM cartridge or game cartridge :The

The CD-ROM format had gained popularity in the 1990s, in the midst of the fourth generation, and as a game media, CD-ROMs were cheaper and faster to produce, offered much more storage space and allowed for the potential of full-motion video. Several console manufacturers attempted to offer CD-ROM add-ons to fourth generation consoles, but these were nearly as expensive as the consoles themselves and did not fare well. Instead, the CD-ROM format became integrated into consoles of the fifth generation, with the DVD format present across most by the seventh generation and Blu-ray by the eighth. Console manufacturers have also used proprietary disc formats for copy protection as well, such as the

External storage

In addition to built-in internal storage, newer consoles often give the consumer the ability to use external storage media to save game date, downloaded games, or other media files from the console. Early iterations of external storage were achieved through the use of flash-based

Nintendo continues to support this approach with extending the storage capabilities of the 3DS and Switch, standardizing on the current SD card format.

Console add-ons

Certain consoles saw various add-ons or accessories that were designed to attach to the existing console to extend its functionality. The best example of this was through the various CD-ROM add-ons for consoles of the fourth generation such as the TurboGrafx CD, Atari Jaguar CD, and the Sega CD. Other examples of add-ons include the

Game development


Console development kits

Console or game development kits are specialized hardware units that typically include the same components as the console and additional chips and components to allow the unit to be connected to a computer or other monitoring device for debugging purposes. A console manufacturer will make the console's dev kit available to registered developers months ahead of the console's planned launch to give developers time to prepare their games for the new system. These initial kits will usually be offered under special confidentiality clauses to protect trade secrets of the console's design, and will be sold at a high cost to the developer as part of keeping this confidentiality. Newer consoles that share features in common with personal computers may no longer use specialized dev kits, though developers are still expected to register and purchase access to

Licensing

Since the release of the Nintendo Famicom / Nintendo Entertainment System, most video game console manufacturers employ a strict licensing scheme that limit what games can be developed for it. Developers and their publishers must pay a fee, typically based on royalty per unit sold, back to the manufacturer. The cost varies by manufacturer but was estimated to be about per unit in 2012. With additional fees, such as branding rights, this has generally worked out to be an industry-wide 30% royalty rate paid to the console manufacturer for every game sold. This is in addition to the cost of acquiring the dev kit to develop for the system. The licensing fee may be collected in a few different ways. In the case of Nintendo, the company generally has controlled the production of game cartridges with its lockout chips and optical media for its systems, and thus charges the developer or publisher for each copy it makes as an upfront fee. This also allows Nintendo to review the game's content prior to release and veto games it does not believe appropriate to include on its system. This had led to over 700 unlicensed games for the NES, and numerous others on other Nintendo cartridge-based systems that had found ways to bypass the hardware lockout chips and sell without paying any royalties to Nintendo, such as by Atari in its subsidiary company Tengen. This licensing approach was similarly used by most other cartridge-based console manufacturers using lockout chip technology. With optical media, where the console manufacturer may not have direct control on the production of the media, the developer or publisher typically must establish a licensing agreement to gain access to the console's proprietary storage format for the media as well as to use the console and manufacturer's logos and branding for the game's packaging, paid back through royalties on sales. In the transition to digital distribution, where now the console manufacturer runs digital storefronts for games, license fees apply to registering a game for distribution on the storefront - again gaining access to the console's branding and logo - with the manufacturer taking its cut of each sale as its royalty. In both cases, this still gives console manufacturers the ability to review and reject games it believes unsuitable for the system and deny licensing rights. With the rise of indie game development, the major console manufacturers have all developed entry level routes for these smaller developers to be able to publish onto consoles at far lower costs and reduced royalty rates.

Emulation and backward compatibility

Consoles, like most consumer electronic devices, have limited lifespans. There is great interest in

The development of software emulators of console hardware is established to be legal, but there are unanswered legal questions surrounding

s, including acquiring a console's firmware and copies of a game's ROM image, which laws such as the United States' Digital Millennium Copyright Act make illegal save for certain archival purposes. Even though emulation itself is legal, Nintendo is recognized to be highly protective of any attempts to emulate its systems and has taken early legal actions to shut down such projects. To help support older games and console transitions, manufacturers started to support backward compatibility on consoles in the same family. Sony was the first to do this on a home console with the PlayStation 2 which was able to play original PlayStation content, and subsequently became a sought-after feature across many consoles that followed. Backward compatibility functionality has included direct support for previous console games on the newer consoles such as within the Xbox console family, the distribution of emulated games such as Nintendo's

Consoles may be shipped in a variety of configurations, but typically will include one base configuration that include the console, one controller, and sometimes a pack-in game. Manufacturers may offer alternate

(SKUs) options that include additional controllers and accessories or different pack-in games. Special console editions may feature unique cases or faceplates with art dedicated to a specific video game or series and are bundled with that game as a special incentive for its fans. Pack-in games are typically first-party games, often featuring the console's primary mascot characters. The more recent console generations have also seen multiple versions of the same base console system either offered at launch or presented as a mid-generation refresh. In some cases, these simply replace some parts of the hardware with cheaper or more efficient parts, or otherwise streamline the console's design for production going forward; the

underwent several such hardware refreshes during its lifetime due to technological improvements such as significant reduction of the process node size for the CPU and GPU. In these cases, the hardware revision model will be marked on packaging so that consumers can verify which version they are acquiring. In other cases, the hardware changes create multiple lines within the same console family. The base console unit in all revisions share fundamental hardware, but options like internal storage space and RAM size may be different. Those systems with more storage and RAM would be marked as a higher performance variant available at a higher cost, while the original unit would remain as a budget option. For example, within the

Pricing

Consoles when originally launched in the 1970s and 1980s were about , and with the introduction of the ROM cartridge, each game averaged about . Over time the launch price of base consoles units has generally risen to about , with the average game costing . Exceptionally, the period of transition from ROM cartridges to optical media in the early 1990s saw several consoles with high price points exceeding and going as high as . Resultingly, sales of these first optical media consoles were generally poor. When adjusted for inflation, the price of consoles has generally followed a downward trend, from from the early generations down to for current consoles. This is typical for any computer technology, with the improvements in computing performance and capabilities outpacing the additional costs to achieve those gains. Further, within the United States, the price of consoles has generally remained consistent, being within 0.8% to 1% of the median household income, based on the United States Census data for the console's launch year. Since the Nintendo Entertainment System, console pricing has stabilized on the razorblade model, where the consoles are sold at little to no profit for the manufacturer, but they gain revenue from each game sold due to console licensing fees and other value-added services around the console (such as Xbox Live). Console manufacturers have even been known to take losses on the sale of consoles at the start of a console's launch with expectation to recover with revenue sharing and later price recovery on the console as they switch to less expensive components and manufacturing processes without changing the retail price. Consoles have been generally designed to have a five-year

, though manufacturers have considered their entries in the more recent generations to have longer lifetimes of seven to potentially ten years.


Competition

The competition within the video game console market as subset of the video game industry is an area of interest to economics with its relatively modern history, its rapid growth to rival that of the film industry, and frequent changes compared to other sectors. Effects of unregulated competition on the market were twice seen early in the industry. The industry had its first crash in 1977 following the release of the Magnavox Odyssey, Atari's home versions of ''Pong'' and the Coleco Telstar, which led other third-party manufacturers, using inexpensive General Instruments processor chips, to make their own home consoles which flooded the market by 1977. The video game crash of 1983 was fueled by multiple factors including competition from lower-cost personal computers, but unregulated competition was also a factor, as numerous third-party game developers, attempting to follow on the success of Activision in developing third-party games for the Atari 2600 and Intellivision, flooded the market with poor quality games, and made it difficult for even quality games to sell. Nintendo implemented a lockout chip, the Checking Integrated Circuit, on releasing the Nintendo Entertainment System in Western territories, as a means to control which games were published for the console. As part of their licensing agreements, Nintendo further prevented developers from releasing the same game on a different console for a period of two years. This served as one of the first means of securing console exclusivity for games that existed beyond technical limitation of console development. The Nintendo Entertainment System also brought the concept of a video game mascot as the representation of a console system as a means to sell and promote the unit, and for the NES was

with the use of Sonic the Hedgehog. The Nintendo and Sega rivalry that involved their mascot's flagship games served as part of the fourth console generation's "console wars". Since then, manufacturers have typically positioned their mascot and other first-party games as key titles in console bundles used to drive sales of consoles at launch or at key sales periods such as near Christmas. Another type of competitive edge used by console manufacturers around the same time was the notion of "bits" or the size of the

used by the main CPU. The TurboGrafx-16 was the first console to push on its bit-size, advertising itself as a "16-bit" console, though this only referred to part of its architecture while its CPU was still an 8-bit unit. Despite this, manufacturers found consumers became fixated on the notion of bits as a console selling point, and over the fourth, fifth and sixth generation, these "bit wars" played heavily into console advertising. The use of bits waned as CPU architectures no longer needed to increase their word size and instead had other means to improve performance such as through multicore CPUs. Generally, increased console numbers gives rise to more consumer options and better competition, but the exclusivity of titles made the choice of console for consumers an "all-or-nothing" decision for most. Further, with the number of available consoles growing with the fifth and sixth generations, game developers became pressured to which systems to focus on, and ultimately narrowed their target choice of platforms to those that were the best-selling. This cased a contraction in the market, with major players like Sega leaving the hardware business after the Dreamcast but continuing in the software area. Effectively, each console generation was shown to have two or three dominant players. Competition in the console market in the 2010s and 2020s is considered an

between three main manufacturers: Nintendo, Sony, and Microsoft. The three use a combination of first-party games exclusive to their console and negotiate exclusive agreements with third-party developers to have their games be exclusive for at least an initial period of time to drive consumers to their console. They also worked with CPU and GPU manufacturers to tune and customize hardware for computers to make it more amenable and effective for video games, leading to lower-cost hardware needed for video game consoles. Finally, console manufacturers also work with retailers to help with promotion of consoles, games, and accessories. While there is little difference in pricing on the console hardware from the manufacturer's suggested retail price for the retailer to profit from, these details with the manufacturers can secure better profits on sales of game and accessory bundles for premier product placement. These all form network effects, with each manufacturer seeking to maximize the size of their network of partners to increase their overall position in the competition. Of the three, Microsoft and Sony, both with their own hardware manufacturing capabilities, remain at a leading edge approach, attempting to gain a first-mover advantage over the other with adaption of new console technology. Nintendo is more reliant on its suppliers and thus instead of trying to compete feature for feature with Microsoft and Sony, had instead taken a "blue ocean" strategy since the Nintendo DS and
