Large companies searching for margin protection in services are branching out into analog businesses (people working with people) that scale poorly.

FORBES: Digital rules

Good programs, however, that do customize for these different learning needs and lead to increased student engagement and time on task, should be easier to scale in a digital world as opposed to an analog one.

FORBES: Colorado's Crummy Policies Lead to Crummy Virtual Schools

That happened on a smaller scale in the 1990s, when manufacturers introduced three incompatible digital sound systems (in addition to the existing analog system).

FORBES: Pixel Perfect

Conventional CMOS image sensors mount the pixel section and analog logic circuit on top of the same chip, which require numerous constraints when wishing to mount the large-scale circuits such as measures to counter the circuit scale and chip size, measures to suppress noise caused by the layout of the pixel and circuit sections, and optimizing the characteristics of pixels and circuit transistors.
