Google seem to argue if it is not clearly write on a ad it is not a hijacking of trademark? But why Google itself stop to put adwords on "verity" one year ago to promote is appliance?
It is logic if a new little unknow "soda company" can buy "coke" adwords to grab the customers of coca-cola who spend billions and billions over years to market their name and that little company will put only a thousands dollars to grab the traffic to his site in a month? Nonsence!
