Sony PlayStation/PSOne
Console Information
The Sony PlayStation began as the SNES
PlayStation, an add-on peripheral for the Nintendo
SNES, but after a dispute between Sony and Nintendo over control
of licences, Sony was dropped from the project. Ken Kutaragi, the
Sony researcher who had worked on the SNES PlayStation (and the
sound chip for the SNES) did not want to give up. He wanted to continue
working on this project and so, after some debate, Sony President
Norio Ogha approved the start of the Sony Computer Entertainment
Division, which would one day account for around half of Sony's
revenues. This was Sony's entry into the world of video game consoles
and would also mean competition for Nintendo.
Kutaragi worked on this secret project to create a
new 32-bit console that was simple yet powerful, easy to program
for and cheap. His original
concept was first shown at the Tokyo International Electronics
Show in October 1991 and due for release in January 1993 for a price
of US$200. The system was still going to allow the play of SNES
games (just like the SNES CD-ROM
that Nintendo and Philips were currently working on) and it was
scheduled for release 6 months before the SNES CD-ROM. Sony's PlayStation
was presented as a console for both games and educational software,
with titles such as: Compton's Enemy Encyclopaedia, Software Toolworks
World Atlas, Microsoft BookShelf 1991, Languages of the World, National
Geographic Mammals of the World and Mixed up Mother Goose. There
were no games announced yet, but with Sony's money and connections
within the video game industry, they were able to get third party
support a little later down the track. Namco was one of the earliest
third party companies to join. They too wanted to get back at Nintendo
for their dispute in 1990. Other third party companies soon joined
as well.
The PlayStation (a.k.a. PSX) as we know it today is much different.
A lot of development was undertaken between 1991 and it's release
date of December 2nd 1994 (for ¥39 800) in Japan. It was then
released in North America on September 9th 1995 (for US$299), selling
over 100 000 units in the first weekend of sale, followed by Germany
(21st September 1995), the rest of Europe (September 29th 1995)
and then Australia (October 13th 1995). Its release was not good
news for Sega,
whose Saturn console had
only just been released. The PlayStation is better than the Saturn
in some ways, but the Saturn still has some technical advantages
over the PlayStation such as the capability to handle more polygons
and better sprite handling in 2D games. But the PlayStation's main
edge over the Saturn was that it was much easier to program for,
thus developers could make great games very easily for the system
and therefore more sales would be made. Unlike the Saturn, the PlayStation
has no built-in memory for saving games. Instead, it relies on Memory
Cards (sold separately, thus making even more money).
The PlayStation was hugely popular due to its huge library of games
(almost 1000) and its cheap price. Just before Sony released the
PlayStation 2, they
also re-released a newer version of the PlayStation called the PSone.
The PSone (released 1999) was a smaller, cheaper version of the
system (both cheaper to buy and cheaper to produce - the system
has no parallel or serial ports), which allowed people who could
not afford the more expensive PlayStation 2 to still get a piece
of the PlayStation action (much like what Nintendo did with the
NES in 1994 and what Majesco did
with Sega's Genesis in
1997). Games for the PlayStation were still continuing to be produced
even after 8 years since the release of the original PlayStation.
