I fully believe that being immune to the time-spiraling nature of social media will become an evolutionary adaptation.

[Eric Seufert @eric_seufert]

“It has gone largely unnoticed that time spent on social media peaked in 2022 and has since gone into steady decline, according to an analysis of the online habits of 250,000 adults in more than 50 countries carried out for the FT by the digital audience insights company GWI.”

If average, user-level social media engagement really has peaked, then investment into AI-enabled advertising targeting and optimization tools is indeed a critical imperative for social media platforms. By extension, a platform’s ability to deploy those investments is a core determinant of growth.

Noticed Amazon is beta-ing ads that take you to a DTC retailer’s site during an emergency pre-Cannes backup 😎sunglasses shopping trip.

Fascinating for retailers with more inventory not stocked by Amazon.

@adamheimlich @AdtechGod I'm going to email you for a chat off X so we can hash it out :). But we are never asked to do anything for sponsors and I'm very proud of the editorial/advertising separation we have at AdExchanger.

[Sarah Sluis @SarahSluis]

@adamheimlich @AdtechGod Come on, Adam! You know AdExchanger. We don't let our sponsors influence our editorial coverage. Full stop.

My big takeaway from Senator Wyden speaking at #IABALM is that National security and national data privacy law cannot and will not be considered separately…at least for now.
