Sony announced today that it will end PSP's comic download service at the end of September. The "comic" tab will no longer be accessible from the PlayStation Store interface after that time.
Ahead of the September closure, Sony will stop adding new content to the service on March 15.
Those who purchased comic content from PlayStation Store will be able to continue redownloading their content through the end of this year. Sony will also keep the Comic Reader app available for download through the end of the year.
For those who'd like to back up their comic content, Sony suggests using the Media Go program.
Sony says that it is currently looking into offering comic and other digital book content through other Sony and PlayStation brand product.
