Balloon advertising involves using giant helium-filled balloons or inflatable shapes to display brand messages and logos high in the sky. These balloons can carry advertising visible from miles away for purposes like new store openings, real estate launches, or local sales promotions. Sky advertising uses aircraft to tow large lettering or billboards at heights of around 1000 feet to reach crowds at festivals, concerts, and other events with high recall branding from the air. Execution details include banner production timelines, size specifications, and flight parameters governed by a contract between advertiser and vendor.
