Sony sent out a message about the the closure of comic books on their Playstation Portable. Comics will no longer be available after October 30, 2012 in the Playstation Store.

After this date users will be unable to purchase comic content from the PS Store’s Comic Store. Where licenses permit, previously purchased or downloaded content will still be available for download until mid- January 2013. After this date users will no longer be able to re-download any previously purchased content. You can, however back up your content using Media Go.

Does that count as another digital comic service out of business? It remains to be seen if someone or something else will fill in the gap.
