The opportunityAn industry that buys constantly and gathers almost never.
Ask a producer how they found their editor and the answer is almost always the same: somebody recommended them. The same goes for the studio they book, the artwork they commissioned, and the platform they moved their back catalogue to after the last one annoyed them.
That is word of mouth doing the work of a marketplace, and it works until it does not. It favours whoever is already known, it breaks the moment you move city or move genre, and it leaves good suppliers invisible to everyone outside one circle of people who happen to talk to each other.
The buying is not centralised either. A show with a hundred thousand listeners and a show with two hundred are both often run by one person choosing a microphone at eleven at night. There is no procurement department to route a supplier to, so a good supplier gets found by referral, at one conference a year, or not at all.
A live expo puts that supply chain in a room. A directory that keeps running afterwards is what stops the introductions expiring when the hall is packed down.
