Though the invention of electricity predates the 20th century, widespread
distribution does not.  Day to day, minute to minute, electricity creates
the 20th Century lifestyle, from 24 hour light ( and 24 hour work day?), to
global media, to skyscrapers, etc.

However, this is still most likely not a valid response as it is not a
single event.
