When did the focus change from IT to SM?

Back in my days at Birds Eye Wall's, then together and part of Unilever, it was all about IT. I helped set up a company-wide screensaver, updated daily with share price, news, photos etc. I worked with a team in IT and the idea of anything being 'social' was ridiculous.

I can't remember when we stopped talking about Information Technology. Maybe some people still do, but I haven't heard the term for ages.

Maybe we're giving less information away now. Have we become more superficial? Is it less about the technology and more about the manner of dissemination?

Or is it just a generational, semantic change?
