We’ve lived with broadcasting for more than a century. Starting with radio in the 1920s, then television in the 1950s, Americans by the millions began purchasing boxes designed to receive electromagnetic signals transmitted from nearby towers. Upon arrival, those signals were amplified and their messages were “aired” into our lives.
Those invisible signals provided our kitchens, living rooms and bedrooms with access to jazz clubs, baseball stadiums and symphony halls. For a century, they have been transporting us instantly to London, Cairo or Tokyo, or back in time to the old West or deep into the imagined future of interplanetary travel.
