MediaBuyerPlanner: With 1.8 million people on its beaches ever Saturday and Sunday during the summer, Long Island's South Shore is the No. 1 market in the country for aerial advertising.

Ted de Reeder, owner of Mattituck-based National Sky Ads, works the area - and many others, Long Island Business News reports. He schedules subcontractors from around the country - including planes and pilots in Miami, Chicago, Houston and Los Angeles - to fly ads for the likes of Domino's Pizza, NASCAR and Toyota.

Customers pay $450 per hour with a two-hour minimum. At a flight level of 1,000 feet, surfers and swimmers can see a banner for an estimated 37 seconds, longer than most TV or radio commercials. Flying billboards have gone from an average size of 25 feet by 50 feet to an average of 40 feet by 100 feet, sometimes even bigger.

Northeast Marketing of Yarmouth, Maine, compiled a survey during a $100,000 State of Maine media blitz promoting a new lottery game. Of those who saw the banner, 88 percent remembered it, and 79 percent remembered what was advertised.
