When I was a child, I sketched a pager with a keyboard and a front screen; at the time I'd seen nothing like it - I think I invented Text Messaging!
Thats my story and immm stickin' to it. Wish I kept that sketch though...
Great article, btw, quite detailed
I'm with Ayyadurai. He did invent "email". BTW I invented "The Steam Engine" (c) 2017 [1]. James Watt? Pssh, never heard of him!
