"A link at the top of [Yahoo]’s front page helped send more than 9 million page views to The New York Times in the span of two hours last week, breaking records for web traffic at the newspaper. ... But as we’ve seen with other news sites, the huge spike didn’t produce much advertising revenue — or, at least, not the copious coin you might expect from traffic at a rate of 7,300 hits per second. That’s because the Times could only serve cheap, remnant ads to its unanticipated visitors."
