Social media is defined as:
a. Has as a sole or primary purpose (disregarding any advertising or revenue- generation purposes) the enablement of online social interactions between two or more end-users; and.
b. Allows end-users to link to, or interact with, some or all of the other end-users; and.
c. Allows end-users to post material on the platform; or.
d. Is otherwise specified in regulations.
That is an extremely wide net to cast. This covers everything from SMS (can post links and interact with others) right through to Facebook et al.
