AI is moving faster. Advertising tools are getting smarter. Brands can do more themselves than ever before.
So why aren't agencies disappearing?
Kelly Sweeney and Sean Wright are back with a Media Monitor Grab Bag, breaking down three advertising headlines that reveal where the market may be heading next.
AI isn't making agencies obsolete
The conversation starts with the growing debate around AI, automation and in-housing.
Programmatic platforms and self-service advertising tools have made buying media far more accessible. AI can process information faster, generate reports and automate work that once required significant manual effort.
But that doesn't necessarily mean brands want to do everything themselves.
Recent industry moves suggest brands still see value in agency and holding-company expertise. Kelly and Sean discuss why the growing complexity of advertising may actually reinforce the role agencies play—particularly when marketing teams would rather focus on customers, creative strategy and brand building than the daily mechanics of media execution.
AI can produce information faster.
That doesn't always mean it makes the decisions easier.
Is 12.3% U.S. ad growth realistic?
Next, Kelly and Sean turn to IAB's revised 2026 U.S. advertising spend forecast, which was raised from 9.5% growth to 12.3% year over year following a strong first half.
Sean sees reasons for caution.
Large advertising businesses posted significant growth during the first half of the year, while major sporting events and other tentpoles helped drive spending.
But underneath those headline numbers, Sean sees a different pattern.
Monthly growth has been slowing, and when major tentpole events are stripped out, the underlying advertising growth visible in Guideline's data is considerably lower.
That raises a central question:
Are forecasts giving too much weight to an exceptional first half while underestimating the economic pressure building in the second half?
Kelly and Sean discuss consumer spending, rising costs, advertising's lag behind economic changes and why the absence of another comparable tentpole later in the year could matter.
Amazon opens another route into AI advertising
Finally, they discuss Amazon's announced partnership with OpenAI, which would allow select U.S. advertisers to run ads in ChatGPT through Amazon's advertising technology.
Many implementation details remain unclear, but Sean sees the announcement as another indication of Amazon's larger advertising ambitions.
Rather than operating solely as the owner of its own media and advertising inventory, Amazon increasingly appears interested in serving as infrastructure through which advertisers can reach inventory elsewhere.
The discussion covers what that could mean for Amazon DSP, OpenAI and the emerging business model surrounding advertising inside AI products.
Plus: Sean accidentally invents his next podcast, Just Angry, Kelly explains why sometimes the smartest AI strategy is knowing when not to build something yourself, and the hosts share details about the new Media Monitor website.
