'Influencer' seems to be a term that's escaped from the marketing corral. Madison Avenue types started identifying Youtubers with a broad reach and approached them about being spokesbeings because they were in the position to influence people.
At that point Influencer=Money.
Now everyone (of that ilk) wants to be an influencer. And the use of the term is shameless.
[edit]There are now Influencer Awards. Big, loud, EDM Award Ceremonies....
