Per this week's story in @NY, Media Unspun is ceasing publication. The newsletter was launched with fanfare by the writers behind The Industry Standard's Media Grok, as a paid-only successor.
At the time they said they expected to get as many as 100,000 subscribers. I blogged back then that while I wished them well, obviously no one had sat down with a circulation marketing expert and a spreadsheet. Because getting 100k paids is expensive and difficult. Not impossible, but not nearly as easy as they expected it to be.
Anyway, now the grand experiment is over. Proving that good editorial and some buzz can sell subscriptions by itself (they claim to have sold more than 5,000) but without a solid marketing plan, you can't fly as far as you'd hoped.
