Last Friday's PS3 launch in the US stimulated a significant rise in PSP and PS2 sales.
For the week ending November 20th, Sony has confirmed that PSP week-on-week sales increased by 29 per cent, while 24 per cent more PS2 units were sold.
The information came from Sony’s top five US retailers, including GameStop and Wal-Mart.
Sony's head of corporate communications David Karraker said the buzz surrounding the PS3 release had provided “a halo effect on other PlayStation products”.
North America’s 400,000 PS3 stock allocation sold out on the day of the console’s launch. Sony expects to have shipped one million PS3 units to the territory by the end of 2006.
