The identity of the original inventor of radio, at the time called wireless telegraphy, is contentious.
A click track is a series of audio cues used to synchronize sound recordings, often to a moving image. The click track originated in early sound movies, where marks were made on the film itself to indicate exact timings for musicians to accompany the film. It can be thought of as a recording of a metronome in that it serves a similar purpose.
Radio is a technology that allows for the transmission of signals by modulation of electromagnetic waves. These waves travel (propagate) through the air and the vacuum of space equally well, not requiring a medium of transport.
Christmas themes have long been an inspiration to artists, writers, and weavers of folklore. Moviemakers have picked up on this wealth of material, with both adaptations of literary classics and new stories. Radio and television have also aggressively pursued entertainment and ratings through their cultivation of Christmas themes.
Many fictional Christmas stories capture the spirit of Christmas in a modern-day fairy tale, often with heart-touching stories of a Christmas miracle. Several have become part of the Christmas tradition in their countries of origin.
