The service is reportedly built around Google's faster-loading AMP mobile webpages (STories + AMP = Stamp). The Wall Street Journal says that news stories on Stamp "could be several swipeable slides encompass text, photos and video."

"Ever since the beginning of AMP we've constantly collaborated with publishers, and are working on many new features," a Google spokeswoman told The Wall Street Journal. It makes sense that Google would want to jump into the fray, with news delivery becoming an increasingly large part of social media and user behavior. Apple has News, Facebook has Instant Articles, and Snapchat, obviously, has Discover.

Ultimately, Google has an advantage over Snapchat, where Discover posts are locked into the app itself. Google can push Stamp stories to search results and other Google products, according to the Journal's sources, just like AMP pages are now; they could also end up on their own publisher's sites, too

When reached for comment, a Google spokesperson responded to Engadget with the following statement. "The success of the open source AMP project is down to the constant collaboration with publishers that involves working early on upcoming features. We don't have anything to announce at the moment but look forward to sharing more soon."
