Google’s ad server is “slow and clunky” — but virtually everybody uses it.

We’re moving through witnesses in the Google ad tech trial, including Stephanie Layser, a former consultant and News Corp advertising VP.

Layser bolstered the DOJ’s claim that Google Ad Manager (formerly Doubleclick For Publishers or DFP) dominates the market thanks to its links to AdX. “DFP is a 25 to 30 year old piece of technology. It’s slow and clunky,” Layser lamented. “It takes a long time to load on the page.”

Day 2 of the Google-DOJ antitrust trial begins.

The Virginia courthouse is a stickler about security, so I’m posting on behalf of Lauren Feiner, who sent the following this morning:

The government didn’t say who would be testifying before court adjourned yesterday, but we left off with several industry players explaining the publisher side of the market. Blissfully, the DOJ said we’re running ahead of schedule already. About to say goodbye to my phone, take my last sip of water (neither allowed in the courtroom!) and head back in.

Google and the Justice Department have made their opening salvos in court.

The government is trying to make this case about Google imposing control over a market, with DOJ counsel Julia Tarver Mason Wood arguing that “Google acquired its way to success.”

Google, meanwhile, says the suit is about the government unlawfully forcing it to deal with rivals. It claims it’s not consolidating three markets, just working in one market with a buy and sell side.

The Google ad tech trial is kicking off this morning.

The Verge’s Lauren Feiner will be reporting on Google’s latest antitrust battle from Virginia, where the Department of Justice will argue that it’s not just a search monopolist, but an advertising monopolist as well.
