10 Mega Corporations of our daily lives

Ten mega corporations control the output of almost everything you buy; from household products to pet food to jeans.

When I purchase any cereal, I know that inevitably, most of them belong to 1 or 2 corporations.
Corporations love to crowd out the market place with all their own products...

but so many of our daily products controlled by 10 corporations?

Wow! Mind boggling.
