Sony Corp has come up with an innovated form of campaign for selling its waterproof MP3 player. Its latest MP3 player comes wrapped within a waterbottle. The MP3 player is said to be launched a few days ago. The MP3 player called W Walkman has a storage capacity of 4 GB.
The promotional campaign suggests the MP3 player can come in handy for athletes and swimmers who are more prone to sweat and water.
