The Trouble with Advertising

Publishing 2.0 on Why Traditional Advertising Formats Fail On The Web (via Kevin Slavin):

Here’s a sobering thought: If all advertising in offline media got converted to current online media CPMs, it would probably be worth a fraction of the value, i.e. $300 billion would become $50 billion.If 1 to 1 transfer of advertising value is at one end of the spectrum and 1 to 0 transfer of classified advertising value to Craigslist is at the other extreme, most of online media is closer to Craigslist — online publishers are vaporizing advertising value in the shift of dollars online.
