In this age of the internet, it is standard practice to search the world wide web using the various search engines such as Yahoo and Google. Did you know however that it is incorrect, indeed objectionable, in trade mark terms to "yahoo" or "google" someone or something – that is, to use these trade marks as verbs thus potentially rendering them generic and the trade mark registrations liable to "death by genericide". Examples of such generic use at one time or another are "hoover", "sellotape" and "escalator".
