On July 27, 1990, HBO aired an episode of Ray Bradbury Theater that revolved around somebody trying to escape from all the noise of omnipresent electronic devices.  The episode was called "The Murderer".  It comes in 3 ten minute parts so it's a bit long but there are some pretty hilarious and prophetic scenes.  This topic came up over at Brighthand in a discussion about how the cell almost always rings when you're in the bathroom.  Thanks DTM for posting the link to this series of videos.  Enjoy (if you can)...
