Thursday\u2019s questioning was a departure from the earlier days of the remedy phase, when buy-side advertiser perspectives were in the spotlight and broader concerns, like generative AI and transparency into Google\u2019s ads business were the focus.<\/p>\n<p class=\"dist__StyledText-sc-1ef9199a-8 zNSXu\">Marketing Brew broke down a few key moments from Thursday\u2019s proceedings below.<\/p>\n<p class=\"dist__StyledText-sc-1ef9199a-8 zNSXu\"><strong>Rocket science:<\/strong> Weissman, a key DOJ witness, seemed to say that from an engineering perspective, a divestiture of AdX or DFP is feasible.<\/p>\n<ul>\n<li>Weissman said that Google\u2019s use of the \u201cseparation of concerns\u201d design principle in its code, which makes it so that changes made in one part of a system won\u2019t affect other parts, could support a successful divestiture.<\/li>\n<li>When it comes to open-sourcing final auction logic, the DOJ has proposed open-sourcing remedies regarding DFP. He pointed to Google\u2019s Android system, which is already open-source.<\/li>\n<\/ul>\n<p class=\"dist__StyledText-sc-1ef9199a-8 zNSXu\"><strong>Back in the day:<\/strong> Google\u2019s cross-examination of Weissman involved questioning the relevance of his credentials as well as matters that could impact the migration of technology if AdX or DFP were to be divested. (As mentioned in Marketing Brew\u2019s coverage of the trial, Google is against an AdX divestiture.)<\/p>\n<ul>\n<li>Google\u2019s lawyers claimed that Weissman had last worked at a tech company in the early 1990s, before the internet or ad tech were widely used. The DOJ pushed back on this later, asking him to discuss his more recent involvement in the tech industry.<\/li>\n<li>Google\u2019s team also quizzed Weissman on his knowledge of modifications that could be needed if AdX or DFP were divested.<\/li>\n<\/ul>\n<p class=\"dist__StyledText-sc-1ef9199a-8 zNSXu\"><strong>Inside baseball:<\/strong> Tim Craycroft, VP and GM of Google Advertising, was next up.<\/p>\n<ul>\n<li>The DOJ\u2019s team questioned him on Project Sunday, an initiative, in which he said that Google had determined it was possible to separate AdX or DFP and that publishers would remain live on the platform throughout the transition.<\/li>\n<li>Internal analyses found that DFP final auction logic could be made open-source, he claimed.<\/li>\n<\/ul>\n<p class=\"dist__StyledText-sc-1ef9199a-8 zNSXu\">Google\u2019s team asked Craycroft about his time overseeing the display ads business for Amazon, where he worked before Google.<\/p>\n<ul>\n<li>Craycroft seemed to confirm that his team had considered building a DFP competitor, but ultimately did not.<\/li>\n<\/ul>\n<div class=\"style__InlineSubscribeWrapper-sc-9b30af34-1 xBGLJ inline-subscribe\">\n<div id=\"inline-subscribe\" class=\"style__RoundedContainer-sc-bac6188c-0 jnRTsW\">\n<h5 class=\"inline-subscribe\">Get marketing news you&#8217;ll actually want to read<\/h5>\n<p class=\"inline-subscribe\">Marketing Brew informs marketing pros of the latest on brand strategy, social media, and ad tech via our weekday newsletter, virtual events, marketing conferences, and digital guides.<\/p>\n<\/div>\n<\/div>\n<p class=\"dist__StyledText-sc-1ef9199a-8 zNSXu\">As the remedy phase begins its second week, the jury\u2019s still out (pun intended) on which witnesses will be prioritized next.
