Sony has launched their new Portable TV rental service for owners of the Sony PSP in Japan. The goal? To make the PSP more than just about gaming, videos and music. Through the use of WiFi support within the PSP, users can now purchase and download video content from Sony's Portable TV network and store them onto their Memory Sticks.

Users will be able to download TV shows, music videos, trailers, and other video programming from Sony's website at a cost of $1 - $3 dollars each. The catch? This is a rental service and not an ownership service. The content will be usable for 1 - 2 weeks and then the videos can no longer be viewed.

The initial video lineup includes popular anime shows like Mobile Suit Gundam, and Noein, and Private Princess: Ayase Haruka. No clue as to whether this service will be made available outside of Japan. Via ExtremeTech.com.
