Almost every newspaper will be on "social media."

If you already use social media like Instagram, you can also read your newspaper there. By tapping on the Instagram logo on your digital newspaper website, you will normally be taken to the newspaper's Instagram feed.

If you don't have a Instagram account, you will have to sign up for one to be able to access your newspaper on Instagram.

Of course, you will not get anything different on the newspaper's Instagram feed, so there is really no reason to use it unless you already have a Instagram account.
