Google’s stepping-up its efforts to stop people from using “google” as a verb. They’ve posted a correct useage guide on the official Google blog, in an attempt to gently persuade people to not use Google incorrectly.
Usage: ‘Google’ as verb referring to searching for information via any conduit other than Google.
Example: “I googled him on Yahoo and he seems pretty interesting.”
Our lawyers say: Bad. Very, very bad. You can only “Google” on the Google search engine. If you absolutely must use one of our competitors, please feel free to “search” on Yahoo or any other search engine.
I applaud the attempt, after all, Google must show that it is at least trying to police its trademark – important, if you want to keep it – but with hundreds of millions of users, it’s unlikely they’ll win this battle.
