June 17, 2025 | SIGN UP Ronan Shields At a recent Digiday virtual townhall held under the Chatham House Rule, media agency professionals discussed the growing uncertainty surrounding demand-side platforms in today’s ad tech landscape. The session highlighted widespread frustration with platform complexity, performance gaps, and the lack of differentiation across DSPs, fueling calls for long-overdue consolidation. Microsoft Advertising’s decision to wind down its Xandr DSP was a key topic, with several participants framing it as one of 2025’s most consequential industry developments. Attendees debated whether its much-publicized Netflix partnership had inadvertently limited Xandr’s broader market appeal and technical evolution. Some argued the relationship may have done more harm than good, stalling innovation and stoking executional challenges that discouraged adoption among buyers. As one agency participant put it, “There were also a lot of issues for those that did activate, and that ultimately reflected most negatively on Xandr, not on Netflix.” ![]() ADVERTISEMENT ![]() Top stories![]() ![]() ![]() ![]() ![]() Other things to know![]() ![]() |
