Google introduced yesterday (13 February 2018) a new Stories format for Accelerated Mobile Pages, which they say is:

"A visual-driven format for evolving news consumption on mobile."

AMP stories are suposed to enable small publishers with small budgets easily to provide a "fast, beautiful experience on the mobile web" by hosting an AMP page on their site, and creating links to drive users there.

Major publishers that participated in the developnment of the format include CNN, Conde Nast, Hearst, Mashable, Meredith, Mic, Vox Media, and The Washington Post.

Publishers can customize the Stories templates for brand identity.

CNN example:

Developers are also working on making AMP Stories findable on Google Search.

AMP Stories are free for anyone to use.

And there's a Wordpress AMP plugin that should work with Stories.

Here are links to Google's AMP Stories tutorial and documentation. These are probably subject to change as more publishers begin to use the format, which Google cautions is "experimental."

Critics worry that AMP Stories make it easier for unscrupulous publishers to create fake news, which I'm sure is the diametric opposite of what CNN et al had in mind when they got involved in this project.

We'll be watching...
