Let's make it easy, we all know majority of companies are subsidiaries of bigger companies. Just pick the company, no need for it's parent company. Example : Disney owns ESPN. YUM foods own Taco Bell. Big part of me wants to select ESPN , but gotta go with Google.
Baker Botts, Cedars-Sinai, Allen & Co, King Ranch, Florentine Films (Ken Burns' company), D.E. Shaw, professor at Rice or UT
I'd wanna work for myself. But since this is like a dream scenario, let's say that I own the Houston Rockets, and have won multiple championships. I wouldn't mind working and picking Morey's brain either. That'd be pretty hardcore interesting actually.
