However, the release of several blockbuster games during the 2001 holiday season pushed the PS2 far in front even as the Xbox and GameCube made their impressive debuts.
Developers also complained that it was difficult to develop for the system, with little in the way of reference material from Sony for its exotic architecture.
These included a PCMCIA slot instead of the Expansion Bay (DEV9) port of newer models.
One of them includes the old EE and GS chips, and the other contains the newer unified EE+GS chip, otherwise being identical.
The PlayStation 2 was such a hot item after its release that it was near impossible to find one on retailer shelves, leaving those wanting a PlayStation 2 to either wait or purchase the console online at sites such as eBay, where the console was being sold by many people for twice and sometimes five times as much as the manufacturers listed price.
It was not until late 2001 that the Microsoft Xbox became the second console with (non-standard) USB and DVD support.
It is unknown whether or not this will follow the.
In September of that year, in time for the launch of Grand Theft Auto: San Andreas (the best-selling game during the 2004 Holiday season), Sony revealed a new, smaller PS2 (see Hardware revisions).
In preparation for the launch of a new, slimmer PlayStation 2 model (SCPH-70000), Sony had stopped making the older PS2 model (SCPH-5000x) sometime during the summer of 2004 to let the distribution channel empty out stock of the units.
PS2's opening day console sales eclipsed the previous record of 225,000 made by the Sega Dreamcast in 1999.
There are also some disputes on the numbering for this PS2 version, since there are actually two sub-versions of the SCPH-70000.
To this day, the PS2 holds the record for the most consoles sold in a single day as well as the record for most consoles sold in launch day in America.
