Time and time again we witness companies putting together ad campaigns that highlight appealing aspects of their products, but how many are actually prepared to stand by those claims? It appears that Sony is on a mission to prove to the New Zealand population that its latest personal MP3 player is indeed waterproof, and have even brought a specialist advertising agency on board to try and get the message across. In conjunction with Auckland based DraftFCB, Sony has concocted the Bottled Walkman campaign that validates the waterproof claims by selling the latest Walkman MP3 player submerged in a bottle of water.
