Someone deserves some credit for drawing up this graph.
An article written by Ashley Lutz on Business Insider link here
According to Ashley Lutz the graph was found on facebook and should be taken with a grain of salt because of how easy it is to trace an individual to a corporation. The graph also does not specify the influence each member had in the company and it is difficult to follow the lines.

Companies That Should Not Be Included
At least one of the companies listed in the graph does not exists any longer. SOHIO, logo as seen in the image below, was bought up by BP and the logo was replaced as far back as 1989.
According to dantiques (link here):
BP replaces the red, white and blue Sohio ovals, once the most recognized logo in the US, with redesigned BP shields 'with an emphasis on the colour green'.BP gets a single Brand Name Wall Street Journal Jan. 6, 1989
If you find more listed in the graph let me know in the comments below.
