Katherine MacLean wrote a story back in 1971, "The Missing Man". It won a Nebula Award that year. It was set in the far distant future, 2013 IIRC. Good story, but one part hit home. People carry "personal TVs" around with them. When Our Hero is on a subway train nobody notices him because they're all staring at their TVs, oblivious to their surroundings.
Nailed it.
