The average person checks their phone 9 times per hour and the average sporting event or concert lasts 3 hours which means each patron will look at the sponsor logo approximately 27 times per event. Multiply that by 15,000 fans and that equals 405,000 impressions per event. And multiply that by 100 events and that equals 40,500,000 annual impressions. This number obviously increases or decreases based on venue size and number of events - but you get the idea.
