On Tuesday, Google ended two and a half weeks of defending its search business against the Department of Justice’s monopoly claims, reportedly with a whimper.

During the DOJ’s cross-examination of Google’s final witness, Kevin Murphy, the economist got “upset” when the DOJ introduced a 2011 email from an ex-Google executive, Chris Barton, which suggested that Google’s default search agreements with wireless carriers, mobile device manufacturers, and browser partners had to be “exclusive,” Big Tech on Trial reported, or else they were worthless.

“Without the exclusivity, we are not getting anything,” Barton’s email said. “Without an exclusive search deal, a large carrier can and will ship alternatives to Google.”
