LikeWar: The Weaponization of Social Media (Houghton Mifflin Harcourt, 2018), by P.W. Singer and Emerson T. Brooking, outlines the history of social media platforms and their use in popular culture and modern conflict. The authors make comparisons to previous technological advancements (such as telegraph and radio) and connect the use of social media to a Clausewitzian view of war. The use of social media by insurgents, criminal organizations, and nation-states raises questions about whether the medium is the message or if new communication channels are propaganda in another form.
