Sony has announced this week that the number of registered accounts on PlayStation Network has now topped 20 million worldwide, compared with 17 million paying subscribers on Microsoft's Xbox Live service.

Unlike Xbox Live, where users have to pay for the Gold membership package, the PlayStation Network is a free service which launched with the PS3 back in November 2006 in Japan and the US.
