Sony Computer Entertainment Europe is to close down its Go! Messenger service due to a lack of users.
Go! Messenger was developed in collaboration with BT, and allowed users to make instant messenging, voice and video calls on the PSP.
"Although Go! Messenger brought innovative communications features to the PSP community, the service has not developed the base of users that we were hoping for," wrote a spokesperson for Sony.
"Although it proved a popular concept, achieving a significant number of registrations, it didn’t gain the number of regular users that BT and SCEE were aiming for."
Go! Messenger was only launched a year ago, and used the Go! Cam on any model PSP.
The service ends March 31. "We’d like to thank all fans of Go!Messenger and are sorry to have to make this announcement," said Sony.
