It's the same for tech, various gadgets or technologies that are hyped right now have been gathering traction since years but have been picked up by the big brands only very recently. Best example is the trend of using non-x86 Computers, a few desktop/laptop projects have been there including Chrome books. Now Apple picked it up and it's a completely normal thing to buy an ARM laptop.
Looks kind of planned but it's not. It's just that some things fall out of fashion for whatever reasons...
