That's because up until recently, Iger was like an Eisner clone. Now he has an exit plan from Disney and wants to leave his legacy. So what does he do? He becomes the anti-Eisner and starts gobbling up big media properties left and right. If you read DisneyWar it certainly paints Eisner as being very anti-acquisition, I think he only begrudgingly did the CapCities/ABC deal and that was because all the other big content providers were acquiring networks too, thanks to the deregulation of the late 90s/early 2000s. I think Eisner knew Disney was toast unless he acquired a network, so his hands were kind of tied.
But that book also details numerous deals that Ovitz or others tried to make that probably would have been very good for Disney, that Eisner would scuttle behind their backs. Toward the end it seemed like Eisner was totally paralyzed by indecision, he didn't want to spend ANY money to buy new stuff, and his own internal creatives were failing him as well, and he didn't want to spend money to help develop things internally either. To be fair, part of it was the great tech bubble burst followed by 9/11, but other companies seemed to navigate that alright. No wonder why Comcast almost took over Disney.
Honestly, I think most of these deals make sense stategically for Disney and will help strengthen the company in the long run. What I hope doesn't happen, is that in the process of doing so, Disney becomes just another media company and loses the foresight, creativity and innovation of its namesake. To me, what always set this company apart from the others was the willingness to dream big and acheive big. That DNA is still there, but it should be promoted more. People like John Lasseter I think are the next guardians of the flame, I hope he and others are training a new generation to continue that mindset.
Wish some of them could be in the boardroom though.
