I use the hotels analogy. Hotels like to sell their rooms up front (or in bulk) but if they're at 80% capacity they start to put rooms out on aggregators like Hotels.com or HotelTonight because a room filled at half price is better than no occupancy.
We do that with digital ads. Big websites like to sell most of their ad space up front but given fluctuations in site traffic there's no way to forecast how much availability there will be at any given time. We work with the software that helps brands buy ads that are available in the moment across the web - but it gets done thousands of times per second on a massive scale.
That said, if the person I'm talking to is in like... construction or some industry that is not tech adjacent at all, I'll just say "i'm in advertising" or "I work with technology that helps brands show ads online".
