Google has become an important roll in modern life. We use it for research, it owns Android, it owns Youtube, and sometimes needed just to ask stupid questions. (Clearly this is not everything from Google, but just off the top of my head.) Pretty much everyone relies on this company nowadays in SOME way. I see commercials saying that you can run an entire business on your Android phone! (Personally, I think that's a bad idea.) Sooo... what would happen if Google shut down? How devastating would that really be? What kind of effect would that have on other big businesses?
Alright, I don't think I got the point across. Along with Google; Youtube, Android, and evrything else on this list would go down with it. They have purchased and merged w/ these companies.
