Brandividuals the term is rather new. Brandividials as a concept, not so much. Brandividiausl as a hybrid role of person-representative? They have been around forever.
your definition refers to brandividual as an “online” personality. By definition, would you consider a personality (who is iconic to their brand) such as Steve Jobs – a celebrity spokesperson or a “brandividual”? Why the focus solely on a brandividual being an artifact of an “online” brand or org?
At some level in a social networking context, aren’t we all brandividuals?”
