Dana VanDen Heuvel reports that CMO Magazine is going dark:

The extraordinary feedback and support from the CMO community has not been enough to sustain and grow our advertising-supported business in what has become a severely challenged publishing environment.

More to the point, they have blogs and are not just old-school publishing folk. These guys really made a run at this.

Is there just not enough of a market for marketing to marketers???

I've been getting CMO for awhile now, and liked it well enough. I think the key issue is that their model assumed that they could get enough advertising support - I was never asked to pay for a subscription. Would I have? I don't know, but they never even asked. Perhaps they should have tried asking for revenue from their readers?
