That's basically my whole lifetime. I don't think the difference was all that stark until online communications moved from message boards and IM clients to social media like Facebook, Twitter, and Instagram, in what, the late 90's/early 2000's, give or take. Before that, technology propelled other changes, but I don't think we saw a wholesale cultural shift until the introduction of the first true smartphones and their accompanying app ecosystems. But yeah, after that, the changes have been sweeping and dramatic, in my view.
