That's really not true. We've been drawing faces and other emoticon-like symbols next to our words long before the internet. (Think informal writing like postcards or notes.) People have illustrated their writing for even longer. (Think medieval manuscripts, as an extreme example.) Even canonically great writers don't (as a whole) limit themselves to words- they write plays that include stage directions, they write poetry that plays with layout and punctuation, they write songs that include melody and instrumental parts. It's really only some forms of formal writing that limits itself to words to convey emotions.
