Yes, it was predicted in some detail in 1945 by Dr. Vannevar Bush. You can read his predictions here: http://www.theatlantic.com/magazine/archive/1945/07/as-we-may-think/303881/. In addition, Nikolas Tesla made some pretty good guesses about cellphones in Oct. 1909: https://books.google.com/books?id=nN8DAAAAMBAJ&lpg=PA476&vq=tesla&pg=PA476&hl=en#v=onepage&q&f=false.

One of the go-to literary sources for the Information Revolution is E.M. Forster's "The Machine Stops", a novella about instantaneous communication and the dangers of social isolation in an information-tech-heavy world. Published in 1909.

Mark Twain also wrote "From The 'London Times' in 1904" (it's in this collection), written in 1898, that's kinda sorta about social media, and very tongue-in-cheek.

It's about the social effects of the invention of the "Telelectroscope," especially how it helps a prisoner feel free... without actually becoming free (and without actually seeing justice done).
