The two comic book giants now have company pages within Google Plus where you can find previews, news, images, and videos about upcoming projects.
Marvel’s Google Plus Page: https://plus.google.com/108523337373444601877/posts
DC’s Google Plus Page: https://plus.google.com/113519537265944504829/posts
So if you are a Google Plus user, you have these options to add to one of your circles. It looks like both companies are committed to populating these pages and keeping the up to date. I’m trying hard to use Google Plus, I see it’s benefits over Facebook clearly. Now at least with DC and Marvel in my social circles I’ll have more content streaming through there.
