About a decade ago I was interviewed for a social media manager role and said the same thing.  They did not approve my take and I knew they would be horrible to work with.  Their concept was that all social media started with Facebook and Twitter (but even Myspace or friendster, let alone icq or forums and they didn't know what Usenet was).  I said "the Internet IS inherently social media no matter the silo" and I guess that went over the head.
