The Constipated Carrier Model
Explain to them that AT&T staked its fortune on the idea that it makes sense to charge more for certain kinds of information, and that it makes sense to charge per-minute. The fruits of this idea are obvious. Despite the fact that AT&T started out with the only nation-wide network of sufficient size and sophistication to act as a (stupendously profitable) modern data carrier, their commitment to the pre-World War I era concept of non-uniform pricing and per-minute billing instead drove them into decline and irrelevance. AT&T was once a powerhouse of American innovation, but its leaders failed to understand the basic economics of their own business. By basic, I mean that applying a small lesson from a high school economics class would have permitted them to save AT&T. They could have just picked up a text on economics, and looked up "network economy" in the index. But they didn't, and as a result, one of America's greatest enterprises crashed and burned, taking tens of thousands of jobs and billions of dollars of capital along with it.
So, now AT&T wants to repeat the great success they've had in the last 20 years, but this time with the entire American information economy.
No thank you.
