I read the article cited here:
Williams, F., Strover, S. and Grant, A. E. (1994). Social aspects of new media technologies. In J. Bryant J. & D. Zillmann (Eds.), Media effects: Advances in theory and research (pp. 463-482). Hillsdale, NJ: Lawrence Erlbaum Associates.
I have substituted their phrase “new media” for “social media”.
