Apple’s foray into video shows limits to tech growth

Apple’s latest move into streaming video illustrates an escalating trend: Tech’s biggest companies, faced with limits to their growth, are encroaching on each other’s turf.

Apple is launching a video-games service and introducing its own credit card. In doing so, it may be veering the most outside its comfort zone.

Even as Apple is taking on Netflix and others, Facebook is edging into Amazon’s sphere with its e-commerce plans. Google, which has already challenged Amazon and Microsoft in cloud computing, is launching an online game service that could undercut the lucrative game-console business at Microsoft and Sony.

Tech industry analysts see new urgency in the latest push into subscription services and other businesses that bring in continuous flows of money.
