Lighting was the killer app for electricity.

  Outdoor lighting in particular, at first at least. A fun historical anecdote on this one most don't know is the saying that somebody "can’t hold a candle to [x]". It's a reference to the old profession of link-boys who were mostly poor kids who'd carry a torch at night for people to see their way about, in exchange for a penny or two.
