Jonathan Tinter, a Microsoft vice president whose job has been to help Bing grow, testified at the trial of the U.S. Justice Department's antitrust case against Alphabet's (GOOGL.O) Google. The department accuses Google of paying $10 billion annually to wireless carriers and smartphone makers to ensure that Google search is the default on their devices. Tinter said that Bing has struggled to win default status on smartphones sold in the United States, and that this smaller scale translated into poorer quality search. "We were just big enough to play but not big enough to win," Tinter said.
