It’s hard to believe that Marvel Studios were once far from a sure thing. (I wrote recently about that, here.) Now that they are a part of Disney, they are a Juggernaut, with rollout plans going on well into the future, as you can see, here: Marvel outlines Phase 6 with Fantastic Four and two new Avengers movies – The Verge.
In some ways the journey is not unlike Apple’s. Apple is such a dominating player now, but back in the 90s it was hanging on by a thread.
It’s possible that both companies could falter, but I suspect we will be getting our fill of Apple Devices and Marvel Entertainment for the rest of this decade. I’ll be curious to visit this post in 5 or 6 years and see if this prediction held.
