After announcing that Facebook Stories ads were coming back in July, The Social Network has this week confirmed that all businesses can now advertise within Facebook Stories, with Messenger Stories (formerly 'Messenger Day') ads also coming soon.
As explained by Facebook:
"Now you can include Facebook Stories as an additional placement to News Feed or Instagram Stories ad campaigns, delivering your message in a fullscreen, immersive environment. And soon, you’ll be able to extend the reach and improve the performance of your stories ad campaigns in Messenger too."
