The biggest bubble in your diagram is Disney. I remember probably around the early 80s, the “Bass Brothers” of Fort Worth, Texas came to their rescue. Disney was threatened with a hostile takeover, and the Bass Brothers stepped in as their white knight. Not sure what their involvement is now, if any. I looked up Robert Bass. Their original fortune was derived from the oil industry, but I see he is now the Chairman of the aerospace company, Aerion Corporation of Nevada.
