TV advertising used to work like this: you sat on your sofa while creatives were paid to throw a bucket of shit in your face. Today you're expected to sit on the bucket, fill it with your own shit, and tip it over your head while filming yourself on your mobile. Then you upload the video to the creatives. You do the work; they still get paid.
Hail the rise of "loser-generated content"; commercials assembled from footage shot by members of the public coaxed into participating with the promise of TV glory. The advantages to the advertiser are obvious: it saves cash and makes your advert feel like part of some warm, communal celebration rather than the 30-second helping of underlit YouTube dog piss it is.
