Tom Standage. Writing on the Wall: Social Media - The First 2,000 Years. Bloomsbury USA, New York, 1st edition edition, October 2013. ISBN 978-1-62040-283-2.
In this article, the author talks about how human communication and social media have evolved over time. The interesting fact I took away from this is that the concept of social media isn't entirely new and has similarities of human traditions in the past.
