You are in an age where modern conveniences were mere pipe dreams. The telephone is tethered to the wall. Your music was heard over a console radio or through a record player. Posted mail took days to reach its destination. And your writing process involved one of these contraptions. You are writing a "futuristic' piece where all of the modern versions of these scenarios come into play. The only catch is you must give these "inventions" different names than we have given them that are more descriptive to their purpose. Everything new is old again for your piece of fiction. Be as outlandish as possible. You may even taken a modern item and back date it in the same fashion.
