Does anyone know where I can find a list of all the brands owned by ultracorporations? (Unilever, nestle, P&G, etc)

Or better yet, a downloadable database that I could work with.

@kboyd i've only seen infographics where all the grocery brands are connected in a tree showing that everything is owned by 3 companies. there was a separate one for car companies. same thing. choice is an illusion, no matter what you buy the same 3 guys get your money.
@bobmagicii this one?  @kboyd
