Interesting statistic of the day...

[xthread]

From Bruce Schneier's article in Forbes about why we're stuck with spam so long as the underlying economics remain the same, the following interesting piece of information:

A 30-second prime-time television television ad costs 1.8 cents per adult viewer; a full-page color magazine ad about 0.9 cents per reader. A highway billboard costs 0.21 cents per car. Direct mail is the most expensive, at over 50 cents per third-class letter mailed... Typically, spammers charge less than a hundredth of a cent per recipient. And that number is what spamming houses charge their customers to deliver spam; if you're a clever hacker, you can build your own spam network for much less money.
