Wikipedia is simply missing information for the other 50%. Many are already in existing products or services e.g. Broadmap, Cue, Acunu.

The others are scheduled for upcoming products. LuxVue for example is widely predicted to be the basis for the new iPhone 8 screen. PrimeSense, Perceptio, Faceshift are all part of Apple's upcoming AR push.

Metaio too

Funny how more than half of them are after 2012. Gotta love the current state of the tech industry.

Substantially more than half of Apple's profits came since 2012. In fact eyeballing it, it looks like their profit in 2015 was bigger than their profit from 1977-2009 combined. https://en.m.wikipedia.org/wiki/History_of_Apple_Inc.#Financ...

You gotta account for inflation

It really doesnt make that big of a difference: https://inflationdata.com/Inflation/Consumer_Price_Index/His...

In Apple's case, no, because their growth over the last decade is insane. But to be clear that table you posted shows that $1 in 1977 is worth $4.40 today. That is a big difference, mostly cause by the insane inflation of 1979-1981 (around 12% a year for three years). That makes the average inflation rate over the last 40 years 4%, which is double our target of 2%.

It's much cheaper to buy promising talent, I mean companies than to devote resources to do your own work from the ground up.
