And if you think there are more commercials breaking up the action on the field than there used to be, you're right. Last year's Super Bowl telecast included a record 45 minutes and five seconds of air time for commercials. But the biggest Super Bowl advertiser is not a carmaker or beer or fast food sponsor. That distinction belongs to the broadcast network (this year CBS) itself, which takes as much as one-quarter of the commercial time to promote its own shows.

The dirty secret of the internet is that all this distraction and interruption is immensely profitable. Web companies like to boast about[…]and so on. But the real way to build a successful online business is to be better than your rivals at undermining people's control of their own attention. Partly, this is a result of how online advertising has traditionally worked: advertisers pay for clicks, and a click is a click, however it's obtained.
