Gen Con 2026 runs in Indianapolis from July 30 through August 2. Event-focused OOH planning around large conventions typically spans the airport, hotels, downtown approaches, transit environments and routes into the convention district.
The planning mistake is to buy only the closest billboard to the venue. Major events create repeated journeys: arrival, hotel transfer, morning commute, dining, nightlife and departure. OOH frequency can be built across that movement pattern. Convention attendees repeat predictable journeys between airports, hotels, the venue, restaurants and nightlife districts. Those repeated paths are where frequency is created, which is why the 'closest board to the convention centre' is rarely the full plan.
For Billboard Guide, the useful way to read the story is not just as a campaign or company announcement. It is a practical example of how the outdoor medium is changing: where advertisers can appear, how inventory is packaged, what creative earns attention in public space and what evidence a buyer should request before deciding that a placement is worth the premium.
Why the calendar matters to OOH
Outdoor planning is unusually sensitive to physical movement, and events temporarily rewrite that movement. A corridor, station or district can become more valuable because people are arriving from the airport, checking into hotels, travelling to the venue and circulating through hospitality areas.
How to build the route plan
Start with origins and destinations rather than a list of available boards. Map airports, rail stations, interstates, hotels, parking, rideshare areas, fan zones and nightlife districts, then identify where multiple audience journeys overlap. Large-format roadside can build arrival impact, transit can add repetition, and place-based DOOH can reach people closer to moments of purchase or entertainment.
Timing and measurement
A campaign does not always need to run for the same period as the event. Arrival and departure days may deserve heavier weight, while digital inventory can be dayparted around gates opening, headline sessions or evening activity. Measurement can include reach and frequency, venue visitation, brand lift, promotional redemption or sales around relevant locations.
