Will Crispin survive Tibet-gate at Groupon?

Groupon has wended its way through several of the stages of Kübler-Ross grieving process, finally arriving at acceptance that its Tibet ad just isn't going to fly. The company said yesterday that it would pull the ad, along with the others mocking celebrity-cause campaigns, in response to the overwhelmingly negative reaction after the Tibet spot aired during the Super Bowl. The move is a blow to the startup, which has been on a remarkable hot streak, and calls into question whether Crispin Porter + Bogusky will be next to get the boot.
