Erm... given how terrible Sony is marketing wise, i wouldnt recommend anyone else to copy them. Also, if what i say doesnt make sense, you dont know what marketing is.
But, im nice so ill give you an example. Vita is a terribly marketed product. It failed to appeal to consumers.
In terms of marketing Nintendo is an example to follow, aswell as the marketing of their games.
Maybe you meant advertising? At wich point, you might have a point. I dont like the light-blue boxes of the WiiU.
