Google (tm) doesn't like you using its trademarked name as a verb. It is wrong to write "Google (this)" or "Google (that)." The correct way is to write "Go to Google.com and search for (this)." The same is true with Xerox, the company that invented the photocopy machine. It is incorrect to use its name as a verb "to xerox a piece of paper." The correct way is to use generic words, such as "to photocopy a piece of paper." Google.com is trying to stop journalists, ad agencies and news sources from using its name as a verb.
