Event cannibalization

Cannibalization hides inside good news. The new regional edition posts strong first-year sales, and nobody checks how many of those exhibitors trimmed their flagship stand to fund it — the same customer's money moved, and the portfolio booked it twice as success. The practical defence is measurement at the account level: track each exhibitor's total spend across the whole portfolio, not per show, and watch what happens to flagship spend when accounts adopt a second event. Same discipline on the visitor side — if a buyer used to attend your international show and now attends only the local clone, the clone's attendance growth cost your flagship its higher-value visitor. The common mistake is structural: sales teams targeted and paid per show have no reason to notice or report that their wins came from a sister event, so cannibalization persists exactly where incentives point away from it. Fix the incentive before blaming the market. One honest nuance: some cannibalization is worth accepting. If a customer was going to split budget toward a regional event anyway, far better it's your regional event than a competitor's — the sin isn't cannibalizing, it's not knowing you are and pricing the new launch's business case as if it were all new money.
