Most of the earliest home video game systems were dedicated consoles, most popularly Pong and its many imitators. Unlike almost all later consoles, these systems were typically not computers (in which a CPU is running a piece of software), but contained a hardwired game logic.
By the end of the 1970s, cartridge-based systems, beginning with the Fairchild Channel F, had risen to prominence during the second generation of consoles due to the success of the Atari 2600, though stand-alone systems such as Coleco's Mini-Arcade series continued to have a smaller presence in the home market up until the North American video game crash of 1983. Since the Nintendo Entertainment System, cartridge-based consoles have dominated the home market up until CD-based consoles such as the PlayStation gained prominence in the mid-to-late 1990s.
Types of dedicated console 
Arcade games 
Developing from earlier non-video electronic game cabinets such as pinball machines, arcade-style video games (whether coin-operated or individually owned) are usually dedicated to a single game or a small selection of built-in games and do not allow for external input in the form of ROM cartridges. Although modern arcade games such as Dance Dance Revolution X and Half-Life 2: Survivor do allow external input in the form of memory cards or USB sticks, this functionality usually only allows for saving progress or for providing modified level-data, and does not allow the dedicated machine to access new games. The game or games in a dedicated arcade console are usually housed in a stand-up cabinet that holds a video screen, a control deck or attachments for more complex control devices, and a computer or console hidden within that runs the games.
Handheld games 
First released in the 1970s, and characterized by games such as Mattel Electronics' Auto Race and Electronic Football, dedicated handheld video games are considered the precursors of modern handheld game consoles. Devoted to one game or a collection or built-in games, dedicated handhelds tend to employ simple VFD or LCD screens although older models often utilized even more primitive arrays of small light bulbs or LED lights to produce calculator-like alphanumerical screens. Dedicated handheld systems typically comprise a screen, a number of control buttons, and a compact body that houses the game engine.
Hunting and fishing games 
Dedicated consoles have appeared for fishing games, where the unit's body itself becomes a specialized controller in the form of a rod and reel. Other dedicated consoles have been released with light guns, for hunting, shooting, and even archery games.
Game watches 
Rising to popularity in the early 1980s, game watches are electronic wristwatches that allow the wearer to access an included video game that uses the display in the watch's face as its screen. Game watch buttons which originally may have been used for setting hour and minute gain secondary functions in relation to the needs of the game.
Plug and play games (Handheld TV games) 
A dedicated console differs from a handheld TV game (or a "plug and play game") in that the latter integrates the video game console with the game controller.
Most modern dedicated home game systems are popularly referred to as "plug and play," because they are based on modern technology which enables the hardware and software of the entire game to be within a single controller, with no separate console at all. Some of these are clones of old games, and are produced in China or Southeast Asia (i.e. Power Player Super Joy III), while others contain licensed games and are distributed in mainstream stores in the West. Of the latter, Jakks Pacific's line of TV Games is among the most famous, which includes re-releases of many vintage games, from arcade classics to Atari 2600 games, as well as games based on currently-popular characters, such as SpongeBob SquarePants. Konami has also released a line of their classic arcade games, including Frogger, on "plug and play" dedicated systems.
The Pelican VG Pocket was an attempt to make a TV game with a backlit color LCD. Dedicated consoles and handheld electronic games with LCD screens that only have one game are rather distinct devices, but the release of the Pelican VG Pocket has blurred the categorization between the two.
Dedicated consoles tend to have appeal over traditional game systems, especially as they often have several games on one system for less than the cost of a single game for a popular console system; thus making some dedicated systems a more economical choice. These games suffer in reputation, however, as quality control is often thought not to be as high as it ought to be.
Modern retrogaming revival 
Beginning with the 2001 release by Toymax (and later Jakk's Pacific) of the Activision TV Games, there has been a revival of interest in dedicated consoles by nostalgia-driven retrogamers. The subsequent 2002 release of the Atari 10-in-1 system prompted speculation of an Atari revival.
In 2002, the Brazilian Sega distributor Tec Toy, rereleased the Sega Master System with numerous games built in. These are not strictly-speaking, dedicated consoles, however, as they also support cartridge-based games. As of 2006, however, no new cartridges are available for sale. Tec Toy also released a portable Sega Genesis, with LCD screen and several games built in, but it has no cartridge port.
In 2004, a miniaturized version of the Atari 7800 home consoles was released with 20 built-in games and no cartridge support. The dedicated console is actually based on a clone of the NES hardware, but running Atari software. A newer version, Atari Flashback 2, is based on actual Atari hardware, and includes some new built-in games developed by modern hobbyist Atari 2600 programmers, as well as old favorite games. It is reported[who?] that, while the new console has no cartridge slot, it is designed such that a knowledgeable person can add one.
