While publishers are quick to remind us that digital comics sales are only a fraction of print sales, growth continues as more outlets emerge. Digital comics were initially restricted to the iPhone but now they can be enjoyed on the iPad, Android, Windows 7, PSP, and perhaps most importantly, on the web using any ol’ browser you like. This month in particular has seen a flurry of activity. Here’s a quick rundown of what’s happened just since July 1st. And there’s bound to be a bunch of big announcements during Comic-Con, which starts tonight for a special preview night and then officially gets underway tomorrow.

• DC Comics now has an app on the Android courtesy of comiXology. (ICv2)
• Upscale comics publisher Top Shelf has over 70 comics now available on iVerse‘s Comics+ app for the iPad, iPhone and iPod Touch. Top Shelf publishes award winning and critically acclaimed graphic novels like the young reader series Owly by Andy Runton, the great Essex County by Jeff Lemire, the Transformers parody Incredible Change-Bots by Jeffrey Brown, a bunch from the brilliant James Kochalka and much more.
