The PlayStation 2 had a difficult start.
PS2's opening day console sales eclipsed the previous record of 225,000 made by the Sega Dreamcast in 1999.
Not only did Sony roll out the PS2 online adapter in late 2002 to compete with Microsoft, several online launch games were first party titles such as SOCOM US Navy SEALS in order to show that Sony was supporting this feature actively.
Due to its thinner profile, it does not contain the 3.5" expansion bay, and therefore does not support the internal hard disk drive but due to the presence of USB 2.0 ports an external USB Hard disk can still be used, and now uses an external power supply, like the Gamecube.
Two propositions were to name the old model (EE and GS, separate chips) V11.5 and the newer model V12, and to name the old model V12 and the newer model V13.
Another major selling point over the Dreamcast was the PlayStation 2's ability to play DVDs, which gained it a presence in electronics stores which did not formerly sell video game consoles.
In some markets it also integrates a modem.
Available in November 2004, it is smaller and thinner than the old version and includes a built-in Ethernet port.
Many analysts predicted a close 3-way matchup between the PS2 and its soon-to-be-released competitors Microsoft Xbox and Nintendo GameCube, noting that the PS2's graphics were inferior but that it had the advantage of a head start, and had a wide assortment of games of every genre (Xbox's strength was in its hardware; GameCube was the cheapest of the 3 consoles).
One of them includes the old EE and GS chips, and the other contains the newer unified EE+GS chip, otherwise being identical.
The PS2 launch seemed unimpressive and gaffe-prone, compared to the well-planned launch of the Sega Dreamcast, which was making a genuine attempt to woo developers and which had better launch titles.
These included a PCMCIA slot instead of the Expansion Bay (DEV9) port of newer models.
V3 has a substantially different internal structure from the subsequent revisions, featuring several interconnected printed circuit boards.
With a price of $299.99 per console, Sony made gross sales of roughly $153,000,000.
