This document compares three social media platforms for sharing media: Facebook allows easy posting of pictures and video to your page for friends to see, like, comment on, and share; Twitter allows adding media that followers can see, like, and retweet so others may see it as well, and it appears on your timeline; Instagram is used to post pictures and videos on your home page for followers to see and allow them to like and comment, and if not set to private then anyone can view the media.
