Lol its Google. What's more to say? Nowadays when we look something up we "Google it" or "I Googled the Second Crusade" or something like that. "I Binged that" just doesn't sound right. Anyways. It is quite biased. Anything related to it will immediately pop up. But then again, it's probably the most used search engine, and it owns YouTube, Gmail and etc. Fast, free, and useful.
