Comment Amazon isn't out of expansion area (Score 1) 168
Amazon isn't out of expansion area. Their target is all of retail, and there's still a lot of non-Amazon retail. Most other big US companies with lots of cash have hit their natural limits.
Trying to go beyond those limits is tough. Google has not been successful in expanding beyond ads. (Android only makes money as an ad platform; Google's phone revenue is small.) Apple has a lot of cash, but can't find any way to use it that will yield the kind of margins Apple is used to. Facebook is still growing, but again, it's all ads.
There's only so much ad spending in the world, and the ad-based companies are all fighting over the same pot. There's more room to grow when your business model is "sell everything".
