High Quality Content by WIKIPEDIA articles! PSX (also known as PlayStation X) was a Sony digital video recorder with fully integrated PlayStation and PlayStation 2 video game consoles. Since it was designed to be a general-function audiovisual device, it was marketed by the main Sony Corporation and was released in Japan on December 13, 2003 . It was the first Sony product to utilize the XrossMediaBar (XMB). The fact that it was extremely expensive resulted in a lack of consumer interest. As a result, like the Nintendo 64DD, another failed item of video game hardware, the PSX was never released outside Japan.
