Advertising at the Beach

Hello! I am a college student writing a paper comparing US beach advertising to other countries. In the US it is very common to have planes flying overhead pulling banners, skywriting, imprints on the sand, people passing out flyers, etc., but what types of advertising are utilized at the beach in other countries? Specifically I'm looking for advertising at the beach, not advertising of a beach (as well as when the type of advertising began).

Any help or links would be much appreciated.

thanks!
