No, it’s no longer just the name of the biggest search company ever. “Google” is now also a verb, and it has entered the mainstream vocabulary as the equivalent of “search,” much to Google’s annoyance. Now “googling” something means searching for that thing, even if it meant searching on Yahoo!, MSN, or elsewhere.

The verb to google, or to Google, depending on the dictionary, means “to use the Google search engine to obtain information on the Internet.” For example, “Mary googled for Wikipedia references.” Compare with grep. This new word arose from the tremendous popularity of the Google search engine.

Google has attempted to discourage use of the word as a verb, fearing the dilution and potential loss of its trademark, like Yo-Yo, Xerox and escalator (see genericized trademark). -Wikipedia

Of course, we would expect Google to have worry that being a verb would dilute the value of their name. But they’re still the biggest search engine today, not to mention one of the fastest growing companies. So they should probably stop worrying too much.
