Jeff Jarvis recounts the decline of a publishing industry cash cow - the TV guide, specifically TV Guide, the US publication that News Corp's just sold at a loss.
I love that phrase, and hereby give notice of re-appropriating it for whenever it seems appropriate. What Jeff says he means by it is that organisations need to watch out for being beholden to "the money machine that blinds you to the strategic imperative for change".
Candidate number one to earn this phrase is advertising's reliance on big creative and buying eyeballs. These cash cows keep agencies from looking too closely at the complexity business, the work of operating on a human level in networks.
