WTF is real-time bidding?

...is a means by which advertising inventory is bought and sold on a per-impression basis, via programmatic instantaneous auction, similar to financial markets.[1] With real-time bidding, advertising buyers bid on an impression and, if the bid is won,[2] the buyer’s ad is instantly displayed on the publisher’s site

Looks pretty neat.
