The PS2 is part of the sixth generation era, and is the best-selling console to date, having reached over 127 million units in sales by the end of 2007. The sixth-generation era (sometimes referred to as the 128-bit era; see "Number of bits" below refers to the computer and Video games This is a list of Video game consoles and Handheld game consoles that have sold or shipped at least one million units  On November 29, 2005, the PS2 became the fastest game console to reach 100 million units shipped, accomplishing the feat within 5 years and 9 months from its launch.

This achievement occurred faster than its predecessor, the PlayStation, which took "9 years and 6 months since launch" to reach the same benchmark. 
Only a few million people had obtained consoles by the end of 2000 due to manufacturing delays.  After its release, it was difficult to find PS2 units on retailer shelves.  Another option was purchasing the console online through auction websites such as eBay, where people paid over one thousand dollars for a PS2. eBay Inc is an American Internet company that manages eBaycom an Online auction and shopping Website in which people and businesses buy and  The PS2 initially sold well partly on the basis of the strength of the PlayStation brand and the console's backward compatibility, selling over 980,000 units by March 5, 2000, one day after launch, in Japan. Events 363 - Roman Emperor Julian moves from Antioch with an army of 90000 to attack the Sassanid Empire, in a 2000 ( MM) was a Leap year that started on Saturday of the Common Era, in accordance with the Gregorian calendar.  This allowed the PS2 to tap the large install base established by the PlayStation — another major selling point over the competition. Later, Sony gained momentum with new development kits for game developers and more PS2 units for consumers.
A notable piece of advertising for the PS2 launch was accompanied by the popular "PS9" television commercial. 9 was to be the epitome of development, toward which the PS2 was the next step. The ad also presaged the development of a portable PlayStation (first released in Japan on December 12, 2004). The PlayStation Portable (officially abbreviated PSP) is a Handheld game console manufactured and marketed by Sony Computer Entertainment.

Many analysts predicted a close three-way matchup between the PS2 and competitors Microsoft's Xbox and the Nintendo GameCube (GameCube being the cheapest of the three consoles and had an open market of games); however, the release of several blockbuster games during the 2001 holiday season maintained sales momentum and held off the PS2's rivals.

Xbox Live (trademarked as Xbox LIVE) is an online multiplayer gaming and digital media delivery service created and operated by Microsoft Corporation Sony adapted in late 2002 to compete with Microsoft, with several online first–party titles released alongside it, such as SOCOM: U.S. Navy SEALs to demonstrate its active support for Internet play. SOCOM US Navy SEALS is a Video game classified as a tactical third-person shooter developed by Zipper Interactive and published by Sony Computer Sony also advertised heavily, and its online model had the support of Electronic Arts. Although Sony and Nintendo both started out late, and although both followed a decentralized model of online gaming where the responsibility is up to the developer to provide the servers, Sony's attempt made online gaming a major selling point of the PS2.
In September 2004, in time for the launch of Grand Theft Auto: San Andreas, Sony revealed a new, slimmer PS2 (see Hardware revisions). Grand Theft Auto San Andreas is a sandbox-style action-adventure computer and Video game developed by Rockstar North In preparation for the launch of a new, slimmer PS2 model (SCPH-70000; also known unofficially as the "PStwo"), Sony stopped making the older PS2 model (SCPH-5000x) during the summer of 2004 to let the distribution channel empty its stock of the units. After an apparent manufacturing issue caused some initial slowdown in producing the new unit, Sony reportedly underestimated demand, caused in part by shortages between the time the old units were cleared out and the new units were ready. The issue was compounded in Britain when a Russian oil tanker became stuck in the Suez Canal, blocking a ship from China carrying PS2s bound for the UK. The Suez Canal is a Canal in Egypt. Opened in 1869 it allows Water transportation between Europe and Asia without circumnavigation During one week in November, British sales totaled 6,000 units — compared to 70,000 units a few weeks prior.  There were shortages in more than 1700 stores in North America on the day before Christmas.

The console also features USB and IEEE 1394 expansion ports. The IEEE 1394 interface is a serial bus Interface standard for high-speed communications and Isochronous real-time data transfer frequently Compatibility with USB and IEEE 1394 devices is dependent on the software supporting the device. For example, the PS2 BIOS will not boot an ISO image from a USB flash drive or operate a USB printer, as the machine's operating system does not include this functionality. An ISO image is an Archive file (aka Disk image) of an Optical disc using a conventional ISO ( International Organization for Standardization By contrast, Gran Turismo 4 is programmed to save screenshots to a USB mass storage device and print images on certain USB printers.

Instead of having a unified, subscription-based online service like Xbox Live, online multiplayer on the PS2 is split between publishers and run on third-party servers. Most recent PS2 online games have been developed to exclusively support broadband Internet access. Broadband Internet access, often shortened to just Broadband, is high-speed Internet access—typically contrasted with dial-up access over a Modem Xbox Live similarly requires a broadband Internet connection.
All online PS2 games released in and after 2003 are protected by the Dynamic Network Authentication System (DNAS). DnaS is a Gene involved in DNA replication.

Also, some unofficial hacks have been made on the PS2 software allowing it to be used as a fully-functional web browser or messenger when connecting to a certain network. The PS2 can also run Linux. Linux for PlayStation 2 is a kit released by Sony Computer Entertainment in 2002 that allows the PlayStation 2 console to be used as a Personal computer
The PS2 has undergone many revisions, some only of internal construction and others involving substantial external changes. These are colloquially known among PS2 hardware hackers as V0, V1, V2, etc. , up to V15b (as of 2008).
The most obvious variations were the changes in the case design. So the PS2 is differentiated between the original case design and the "slimline" model, which was introduced at the end of 2004. In November 2007, Sony announced a new, physically smaller, version of the slim PS2. 
Three of the original PS2 launch models (SCPH-10000, SCPH-15000, and SCPH-18000) were only sold in Japan, and lacked the expansion bay (Dev9) of current PS2 models. These models included a PCMCIA slot instead of the Dev9 port of newer models. In Computing, PC Card (originally '''PCMCIA''', or PCMCIA Card is the Form factor of a peripheral interface designed for Laptop computers A PCMCIA-to-Dev9 adapter was later made available for these models. SCPH-10000 and SCPH-15000 did not have a built-in DVD movie playback and instead relied on encrypted playback software that was copied to a memory card from an included CD-ROM (normally, the PS2 will only execute encrypted software from its memory card, but see PS2 Independence Exploit). The PS2 Independence Exploit allows the execution of homebrew programs on an unmodified PlayStation 2. V3 had a substantially different internal structure from the subsequent revisions, featuring several interconnected printed circuit boards. A printed circuit board, or PCB, is used to mechanically support and electrically connect Electronic components using conductive pathways or traces As of V4 everything was unified into one board, except the power supply. V5 introduced minor internal changes, and the only difference between V6 (sometimes called V5. 1) and V5 is the orientation of the Power/Reset switch board connector, which was reversed to prevent the use of no-solder modchips. A modchip (short for modification chip) is a small electronic device used to modify or disable built-in restrictions and limitations of many popular Videogame consoles V7 and V8 included only minor revisions to V6.
Assembly of the PS2 moved to the People's Republic of China during the development of V9 (model numbers SCPH-50000 and SCPH-50001). Talk People's Republic of China) PEOPLE'S REPUBLIC OF CHINA ARTICLE GUIDELINES The upgraded console added an infrared port for the optional DVD remote control, removed the IEEE 1394 port, added the capability to read DVD-RW and DVD+RW discs, added progressive-scan output of DVD movies, and added a quieter fan. Infrared ( IR) radiation is Electromagnetic radiation whose Wavelength is longer than that of Visible light, but shorter than that of A remote control is an electronic device used for the remote operation of a Machine. V10 and V11 were only minor revisions to V9.
The PS2 standard color is matte black. Several different variations in color have been produced in different quantities and regions, including ceramic white, light yellow, metallic blue (aqua), metallic silver, navy (star blue), opaque blue (astral blue), opaque black (midnight black), pearl white, Sakura purple, satin gold, satin silver, snow white, super red, and transparent blue (ocean blue). 
The small PlayStation logo on the front of the disc tray could be rotated ninety degrees clockwise, in order for the logo to be the right way up in both vertical and horizontal console orientations.
In September 2004, Sony unveiled its third major hardware revision (V12, model number SCPH-70000). Available in November 2004, it is smaller, thinner, and quieter than the older versions and includes a built-in Ethernet port (in some markets it also has an integrated modem). Ethernet is a family of frame -based Computer networking technologies for Local area networks (LANs Modem (from mo dulator- dem odulator is a device that modulates an analog carrier signal to encode Digital information Due to its thinner profile, it does not contain the 3. 5" expansion bay and therefore does not support the internal hard disk drive.

The, often abbreviated as GCN, is Nintendo 's fourth home Video game console and is part of the sixth generation console era. Multi-tap also refers to a text-entry system for mobile phones The removal of the expansion bay has been criticized as a limitation due to the existence of titles such as Final Fantasy XI, which require the use of the HDD. also known as Final Fantasy XI Online, is a Massively multiplayer online role-playing game (MMORPG developed and published by Square (later Square The official PS2 Linux also requires an expansion bay to function. Linux for PlayStation 2 is a kit released by Sony Computer Entertainment in 2002 that allows the PlayStation 2 console to be used as a Personal computer Currently only the modified MultiTap is sold in stores, meaning that owners of older PS2s must find a used or non-Sony MultiTap in order to have 4 or 8 players during a single game. Third-party connectors can be soldered into the unit giving hard drive support, however IDE connections were completely removed in the V14 revision, thereby eliminating this option.
There are some disputes on the numbering for this PS2 version, since there are actually two sub-versions of the SCPH-70000. One of them includes the old EE and GS chips, and the other contains the newer unified EE+GS chip, but otherwise they are identical. Since the V12 version had already been established for this model, there were some disputes regarding these sub-versions. Two propositions were to name the old model (with separate EE and GS chips) V11. 5 and the newer model V12, and to name the old model V12 and the newer model V13. Currently, most people use V12 for both models, or V12 for the old model and V13 for the newer one.
The V12 model was first released in black, but a silver edition is available in the United Kingdom, Germany, Australia, France, Italy, South Africa, and most recently, North America. The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom, the UK or Britain,is a Sovereign state located Germany, officially the Federal Republic of Germany ( ˈbʊndəsʁepuˌbliːk ˈdɔʏtʃlant is a Country in Central Europe.

Italy (Italia officially the Italian Republic, (Repubblica Italiana is located on the Italian Peninsula in Southern Europe, and on the two largest It is unknown whether or not this will follow the color schemes of the older model, although a limited edition Pink PS2 has become available since March 2007.
V12 (or V13) was succeeded by V14 (SCPH-75001 and SCPH-75002), which contains integrated EE and GS chips, and different ASICs compared to previous revisions, with some chips having a copyright date of 2005, compared to 2000 or 2001 for earlier models. It also has a different lens and some compatibility issues with a different number of PlayStation games and even some PS2 games.
In the beginning of 2005 it was found that some black slimline console power transformers bought between November and December 2004 were faulty and could overheat. The units were recalled by Sony, with the company supplying a replacement model made in 2005.
Later hardware revisions had better compatibility with PlayStation games (Metal Gear Solid: VR Missions operates on most silver models); however, the new Japanese slim models have more issues with playing PlayStation games than the first PS2 revisions.
In 2006, Sony released the latest hardware revisions (V15, model numbers SCPH-77001a and SCPH-77001b). It was first released in Japan on September 15, 2006, including the Silver limited edition. Events 668 - Eastern Roman Emperor Constans II is assassinated in his bath at Syracuse Italy. Year 2006 ( MMVI) was a Common year starting on Sunday of the Gregorian calendar. After its release in Japan, it was then released in North America, Europe, and other parts of the world. The new revision uses an integrated, unified EE+GS chip, a redesigned ASIC, a different laser lens, an updated BIOS, and updated drivers.
In July of 2007, Sony started shipping a revision of the slimline PlayStation 2 (SCPH-79000) featuring a reduced weight of 600 grams compared to 900 grams of the SCPH-77001, achieved through a reduction in parts. The unit also uses a smaller motherboard as well as a custom ASIC which houses the Emotion Engine, Graphics Synthesizer, and the RDRAM. The Emotion Engine is a CPU developed and manufactured by Sony and Toshiba for use in the Sony PlayStation 2 Video game console Direct Rambus DRAM or DRDRAM (sometimes just called Rambus DRAM or RDRAM) is a type of synchronous dynamic RAM, designed by the Rambus The AC adaptor's weight was also reduced to 250 grams from the 350 grams in the previous revision.  This revision is currently shipping in retail game stores. Another refinement of the slimline PlayStation 2 (SCPH-90000) was announced for release in Japan on November 22, 2007, with an overhauled internal design that incorporates the power supply into the console itself, with a further reduced total weight of 720 grams. Events 498 - Kofi Aseidu- After the death of Anastasius II, Symmachus is elected Pope in the Lateran Year 2007 ( MMVII) was a Common year starting on Monday of the Gregorian calendar in the 21st century. 
Sony also manufactered a consumer device called the PSX that can be used as a digital video recorder and DVD burner in addition to playing PS2 games. PSX was a Sony Digital video recorder with fully integrated PlayStation and PlayStation 2 Video game consoles Since it was designed PSX was a Sony Digital video recorder with fully integrated PlayStation and PlayStation 2 Video game consoles Since it was designed A digital video recorder ( DVR) or personal video recorder ( PVR) is a device that records video in a digital format to a Disk drive or other The device, which was only released in Japan, was poorly received, with some major features absent from the first revisions of the hardware, and has thus far experienced very weak sales in Japan, in spite of major price drops. For a topic outline on this subject see List of basic Japan topics.  The machine's future continues to be uncertain, with North American and European launches considered to be distant, if at all, especially since the release of the PlayStation 3.

Some third party manufacturers have created devices that allow disabled people to access the PS2 through ordinary switches etc. One such device is the PS2-SAP from LEPMIS.
Sony released a version of the Linux operating system for the PS2 in a package that also includes a keyboard, mouse, Ethernet adapter and HDD. Linux for PlayStation 2 is a kit released by Sony Computer Entertainment in 2002 that allows the PlayStation 2 console to be used as a Personal computer Linux (commonly pronounced ˈlɪnəks In Computing, a keyboard is an Input device partially modelled after the typewriter keyboard which uses an arrangement of buttons or keys In Computing, a mouse (plural mice, mouse devices, or mouses) Ethernet is a family of frame -based Computer networking technologies for Local area networks (LANs A hard disk drive ( HDD) commonly referred to as a hard drive, hard disk, or fixed disk drive, is a Non-volatile storage device Currently, Sony's online store states that the Linux kit is no longer for sale in North America. However as of July 2005, the European version was still available. The kit boots by installing a proprietary interface, the run-time environment, which is on a region-coded DVD, so the European and North America kits only work with a PS2 from their respective regions.

Owners of early PS2 models purchased from launch until July 2003 often reported faulty optical drives in their consoles. In Computing, an optical disc drive ( ODD) is a Disk drive that uses Laser light or electromagnetic waves near the Light spectrum  The earliest drives suffered from a constantly misaligning laser lens, which could also result in discs being scratched by the lens. A laser is a device that emits Light ( Electromagnetic radiation) through a process called Stimulated emission.  Later defects were the result of a shift in voltage to the laser. Electrical tension (or voltage after its SI unit, the Volt) is the difference of electrical potential between two points of an electrical The first problem was easily remedied by opening the console's casing and tweaking a cog that controlled the lens's distance from the disc; however, this action voided the console's warranty. In commercial and consumer transactions a warranty is an Obligation or guarantee that an article or service sold is as factually stated or legally The second problem could be fixed by using an oscillator. Oscillation is the repetitive variation typically in Time, of some measure about a central value (often a point of Equilibrium) or between two or more different states After many consoles had broken down, a class action lawsuit was filed against Sony. In law a lawsuit is a civil action brought before a Court in which the party commencing the action the Plaintiff, seeks a legal or equitable remedy is a multinational conglomerate corporation headquartered in Minato Tokyo, Japan, and one of the world's largest Media conglomerates with Sony agreed to provide free repair or replacement for the faulty consoles and continued to do so until February 2005.
Another problem that could cause a disc read error is wear on the coupling in the head assembly to the worm gear that moves the laser. A worm drive is a gear arrangement in which a worm (which is a gear in the form of a screw) meshes with a worm gear (which is A symptom of this is a loud repetitive clicking sound. This sound can also be heard on older systems when playing game format or PS1 disks. These problems rarely occur on newer consoles.
A class action lawsuit was launched in 2005 against Sony with regards to this issue. It was settled  by allowing those who purchased a defective console to receive $25, a free game, free repairs or a new console.
Before the PS2 was even released in Japan, there were controversies over the capabilities of the PS2. Japan initially imposed export restrictions on the PS2. The PS2 was even said to contain parts, especially its powerful graphics hardware, which could be used to simulate the effects of military ballistic missiles. 
The specifications of the PlayStation 2 console are as follows, with hardware revisions:
