Google antitrust trial: Documents say one thing, witnesses something else

The judge who will decide whether Google holds a monopoly over technology that matches buyers and sellers of online advertising must choose whether to believe what Google executives wrote or what they have said on the witness stand.

The Justice Department is wrapping up its antitrust case against Google this week at a federal courtroom in Virginia. The federal government and a coalition of states contend Google has built and maintained a monopoly on the technology used to buy and sell the ads that appear to consumers when they browse the web.
