You never heard of this company? Come on, even in those far away countries where they have little access to TV or Internet, they have heard of this company. Mostly associated with petrol. Yes, those golden liquid that you pump into your vehicle to make them magically move. Shell is the market leader in the United States with over 25,000 gas stations. And not only just petrol, they make all sorts of chemicals as well. From engine oils to grease to all sorts of lubricants. And don't think that these are not important. Refining petroleum products are some of Shell's core business, other than oil field exploration and mining. Those oils you see, goes into nearly every single moving part of nearly every machine in the world. Your car, your water pump, your generator and so on. Probably why Shell is one of the largest corporations around the world. Nearly every single machine need their products in order to work. And as why their name is "Shell"? I am not too sure why. Their logo is of course a shell.
