Jerry Neumann on online advertising pricing: Media has always been an attention economy, Two (More) Hypotheses on Low Online CPMs and Details, details. "The online CPM is the above number divided by impressions per hour. Note that the online spend/hour is pretty steady from 2002 to 2008, between $58 and $66 per thousand hours. The decline in online CPMs can't be attributed to this, unless there was a large increase in ads/hour. This may be so (I can think of arguments both ways, but have no idea what the facts are) but who cares, really? If I spend an hour on the NYT site and they show me 30 ads at a $2 CPM or 6 ads at a $10 CPM, they make the same amount of money: I assume they show the number of ads that maximizes their revenue."
