Lots of comic book retailers are understandably worried about DC’s new move to post its books for sale on comixology the same day they are released in print. Several years ago Marvel had the first 20 or so issues of Ultimate Spider-Man on its website for free. I read those, enjoyed them very much, and have been buying the series ever since, along with several other books written by the same author. I’ve also gone back and bought the issues I read online for free. I may not have ever read that book if I hadn’t gotten hooked and caught up on the storyline otherwise.
