PocketStation
Playstation peripheral developed by Sony Computer Entertainment
The PocketStation is a memory card peripheral by Sony Computer Entertainment for the PlayStation home video game console. It was released in Japan in 1999. The device acted not only as a memory card but was interactive itself via a small monochrome LCD and buttons on its case. Many PlayStation games included software that could be downloaded and played on the PocketStation. A release in Europe and North America was planned but was ultimately canceled. The PocketStation shares similarities with Sega's VMU for the Dreamcast.

Why this record matters
The phrase “playstation peripheral developed by Sony Computer Entertainment” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Apr 27, 2026. The linked authority identifier is Q1147129. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1999 and 1998.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
