"... It's clear that government regulators and some advertisers continue to have concerns about the agreement. Pressing ahead risked not only a protracted legal battle but also damage to relationships with valued partners. That wouldn't have been in the long-term interests of Google or our users, so we have decided to end the agreement."

– David Drummond, Senior Vice President, Corporate Development and Chief Legal Officer, Official Google Blog, "Ending our agreement with Yahoo!"
