The title points to M Radio, a French radio station, and réveil is the French word for wake-up, which explains why the clip is associated with mornings even though its exact broadcast origin is not documented. Short station stings like this travel well online because they are instantly recognisable as radio branding and can be dropped into almost any edit. Its sub-second length also suits modern short-form video, where a single sharp cue can set the time of day without slowing the pace.
