I don't know what the baseline is for CEO popularity (I guess most people don't know that many CEOs by name?) but I'd be hard-pressed to call a 37/50 favorable/unfavorable ratio popular: https://www.natesilver.net/p/elon-musk-polls-popularity-nate...

Maybe he's no longer popular, but he had a cameo in Iron Man 2 and hosted SNL. That speaks to popularity.

Also, is favorable/unfavorable a good measure of popularity?
