Measurement & Honesty

Measuring visibility truthfully, and refusing the numbers that lie.

The Dot-Com Eyeballs Bubble and the Metric That Broke the Market

Between 1995 and March 2000, Wall Street priced internet stocks on "eyeballs," unmonetized page views with no buyer and no auditor. The correction that followed erased 600 percent of gains and reset what the world counted as sellable attention.

The Nielsen Rating Point Becomes a Financial Instrument

In 1962, ABC invented the televised "upfront" to presell a season of airtime before it aired, and cost-per-point buying turned Nielsen's rating into a number precise enough to move hundreds of millions of ad dollars on a single decimal.
