Iger is reeeaaaally into technology and maybe his MyMagic+ was his way of making his two officially named potential successors (Rasulo and Staggs) seem less attractive to take his place. That way he can remain on as a $30-million a year CEO/Churro of the Board for even longer. He did just get a contract extension. Two or three years ago it was thought that Staggs would replace Iger when his contract ended.
The late Roy Disney, Jr. twice helped Disney get new head honchos. If the biggest shareholder--Steve Jobs' widow--and the famous second-biggest shareholder, George Lucas, some Disney family members, and that Marvel guy teamed up they could get Disney fresh leadership. Isn't Steve Burke's contract up soon? Or how about Alan Horn? Or Katzenberg if he sells his Dreamworks Animation share to Universal? Or Lasseter in the visionary Walt/young Eisner role with Staggs as his #2 Frank Wells guy?
The current main purpose of the Disney company is the short-term goal of getting Bob Iger $30 million a year for as long as possible. The comfortably wealthy Iger is articulate and extremely charming with former weatherman TV skills, but he needs to spend more time with his family and explore other opportunities.
