Technology Adoption Curves, then and now.
There's a fascinating out of print book called *Forecasting the Telephone* that I happen to own. It's amazing that many of the things that we use today were predicted over 100 years ago.
If you search you can find pdf excerpts. Here's the growth of telephones year over year. Note that it omits the first 20 years of growth, when phone wires needed to be 1/8" thick.
It might be interesting to chart Google Fiber deployments against this.
