Heinz writes with an article in Forbes on how advertising in tech media is drying up and going — where else? — into specialist blogs and Google. "Silicon Valley is booming again. But if you work in tech media, there's blood on the floor. Take Red Herring. It hung onto its offices after getting the eviction notice earlier this month. But gossip site Valleywag is breaking story after story not just on its beat — but about its woes. Meanwhile, bigger publications are hurting too: Time Warner's Business 2.0 saw ad pages drop 21.8% through March from the same period a year ago; PC Magazine's editor in chief walked out the door after ad pages fell 38.8% over the same period; and one-time online powerhouse CNET is reporting growing losses even as the companies it covers flourish. It may be happening in tech first, but there's no reason the same thing won't happen, eventually, in every media niche."
