A short time ago, Instagram changed "Stories" with a new version. It simply helps you to post a collection/slideshow of images or videos that disappears after 24 hours if you wouldn't know how much an Instagram or Snapchat story is.
Instagram posts may be replicated, but companies have been given a forum that serves an immense role in their digital marketing campaign.
