NZ online retailer Fishpond is dipping into the vast ocean of collective intelligence.
They sell DVDs, and people often choose a DVD based on the trailer of a movie.
Option A: pay a web developer to embed trailers on the site. Very costly.
Option B: pay your affiliates 20 cents for each trailer they embed. Affiliates only do it if they want to, they find trailers for the movies they really really like, and they at least get paid something for it (albeit not a lot).
