Hot of the press, the NY Times has an article about the whole Chevy incident, quoting a spokesperson from Chevy:

A spokeswoman for Chevrolet, Melisa Tezanos, said the company did not plan to shut down the anti-S.U.V. ads.

„We anticipated that there would be critical submissions,“ Ms. Tezanos said. „You do turn over your brand to the public, and we knew that we were going to get some bad with the good. But it’s part of playing in this space.“

And further down they quote Drew Neisser of Renegade Marketing:

companies had such a strong desire for user-generated advertising that they were willing to accept the risks. „There’s this gold rush fever about consumer-generated content,“ he said. „Everybody wants to have consumer-generated content, and Chevy Tahoe doesn’t want to be left behind.“

Hey, it’s the new fad amongst marketeers! Not bad, this trend. I like these kind of campaigns anyway!

(Even though I can’t be moved to participate – yet!)
