The field of art therapy's social media history is a lot older than you think! I started presenting about art therapy and cyberspace in 1995; I officially started writing about it for publication in 1996 and in 2000, Art Therapy and Computer Technology: A Virtual Studio of Possibilities was published by Jessica Kingsley/London. In Chapters 1 and 3 in that book I compiled what was known about "electronic communication" and art therapists, a precursor to what eventually became known as "social media" in the 21st century. Here are some of those earliest publications for download and use in your own research citations about art therapy, digital communication and and social media. ~~ Cathy Malchiodi, PhD
From the article introduction: "Cyberspace is a familiar catch-all phrase for the infinite work of computer networks that include the Internet and the World Wide Web. The Internet or "the Net" is the mother of all computer networks and was originally developed for communications purposes by the US Department of Defense in the 1960s." Read more here about how art therapists in the 1990s began to communicate electronically-- a pre-cursor to today's social media communication.
These excerpts from Art Therapy and Computer Technology (Malchiodi, ©2000) document and illustrate the timeline for the emergence of the pre-cursors to art therapy and social media; this is the earliest and only pre-social media documentation in print listing the chronology of art therapy electronic networks, cyber-groups and online communications.
