@RioLongacre @aripap I took a terrible photo, but it’s Jeff and Ari.

@aripap 🍿

Is there a Polymarket for whether Jeff Green shows up for #marketecturelive today?

@JudSpencer I remember doing interviews to research what the definition of SPO in 2021 - oh boy was that a mess.

I’m calling it. The term “agentic” in ad tech is now worthless. Gone the way of SPO. It’s a PR term with no specific meaning.

I got my copy of Yield signed by @aripap at @marketecturetv Live! Great event!

2/2 and @CaliforniaDCA. Bought new at Costco (Mar 2020, $2,099+tax). Failure began Oct 2025. 4 repair visits. LG spec sheet states “Sealed System 7 Years” here: lg.com/us/support/pro…

1/2 @LGUSSupport 5-month saga: my LG LMXS28626S has a sealed-system leak and your authorized tech says it’s unrepairable. Your team claims sealed-system warranty is 5 years, but LG’s own doc says 7 years. Honor it with full refund or I will file complaints with @AGRobBonta

In case you missed it, here are the details on Commitments Hub that we launched last fall: advertising.amazon.com/resources/what… If you're an advertiser managing spending agreements with publishers, I'd love to connect.

Happy New Year! 🥂 Starting Year 5 at Amazon Ads. Proud of what my teams have shipped to help customers: creative tools for Fire TV self-service performance advertisers, PG deals and O&O deals-based buying in Amazon DSP, and Commitments Hub. Excited for what’s next in 2026!

@aripap Do you have TIDs on the slides or something?

Event feedback: “Ari reused slides from his talk at the prebid summit which I don’t appreciate since I bought a ticket to come here, even though I wasn’t at the prebid summit …”

@jslee @101Programmatic Interesting - how would this work? Would one setting be "I absolutely need to spend $10M in 2025 with Pub Y - prioritize all my spend to make that happen", while another setting would be "Please do your best to spend $10M in 2025 with Pub Y?" What would the trade off be?

@101Programmatic The priority layer on top would be awesome to set for agencies and advertisers wanting to make year long promises or intentions to spend with specific publishers. Someone will do it…

TTD Deal Desk - What This Update Is About (and My First Impressions) I just got access to Deal Desk, and it looks like a really solid update that changes how PMPs and PGs are managed in the platform. Before diving into what Deal Desk is, let’s take a quick step back and look at how deal management worked before. Previously, it was pretty straightforward - and I’d say common across DSPs. You could see all deals, their avails, actual CPM, floors, create new deals, etc. Now, Deal Desk introduces a few new features: - Introduction of “Endeavors” and “Commitments” deals - I’m not fully sure I get this yet, since it seems like everyone will still use PMP/PG instead of the new terms. Maybe I’m missing the bigger idea here. - Direct messaging with sellers - You can now message sellers to request changes. But you can no longer edit or create deals yourself. TTD says this shift is to improve transparency and simplify workflows by moving all deal edits to sellers. - Quality Score - This is the biggest and most valuable update in my opinion. Quality Score is designed to help buyers understand whether a deal offers better value or access than buying the same inventory through marketplace options like the open market or SP500+ The score is based on four signals: 1. Price competitiveness - compares the deal’s CPM to what you typically pay for similar inventory through marketplace options. 2. Addressability - shows what proportion of avails in the deal can be linked to a user or household ID in an identity graph. 3. Signal fidelity - measures how much detail the deal provides about its inventory. 4. Inventory exclusivity - measures how much of the inventory is exclusive to the deal. This actually gives buyers more visibility into what they’re really buying. For example: if a seller claims to offer unique inventory, but the deal shows 0 exclusivity (meaning you can buy the same inventory everywhere else), that’s a red flag and a sign to look elsewhere. It’s worth noting that not every low score means bad inventory. For example, if you’re working with contextual or audience providers, scores like exclusivity and price competitiveness might come in low - but that doesn’t mean those deals aren’t valuable. The data needs to be interpreted in context, based on the seller and your specific goals. Overall, I really like this update. It brings more clarity, transparency, and buyer power into the deal-making process.

@patio11 @pitdesi @SwiftOnSecurity Wait this thread started off about the ease and cost of getting lens prescriptions (licensing). But that seems separate from the cost of getting *frames*

@pitdesi @SwiftOnSecurity Approximately accurate quote for Japan too. I had to restraint myself from getting ten frames for the price of my last U.S. one.

Eyeglasses aren’t opioids. There’s no reason we should need to see an optometrist to buy glasses. You don’t in the rest of the world, and you didn’t in the US either until optometrists lobbied aggressively under the banner of “public safety.” For decades, opticians, trained with just a few weeks of coursework, tested vision and sold glasses directly, just like they still do in Europe, Asia, and most of the world. Outside the US, vision correction (opticians) is kept separate from medical eye care (ophthalmology). In the US, we created the field of optometry and then they lobbied hard to take over vision correction because there is more money in selling glasses than in doing medical tests. By the 1970s, every state required prescriptions, shutting out opticians and cementing an optometrist monopoly. The result: in Europe you can walk into a shop, get tested, and leave with glasses for about $50 all-in. In the US, you are forced into a $200 exam and $300 frames. What should be simple and cheap has been turned into a racket, and consumers pay the price. Much like barber licensing (some states require 2,000 hours of training just to braid hair), this kind of gatekeeping drives up costs without protecting consumers. Vision correction should be cheap and accessible, not locked behind a monopoly!

@JudSpencer A joke that didn't land at all.

@dtc ???

This is one of the dumbest things I’ve ever read.

I led the team that launched PG buying at Amazon DSP - and it sounds like our fee is pretty popular! There's much more to come from Amazon DSP, so stay tuned...

@MichaelSFBA Uh oh did she forget to tag off and get charged from St Pancras to Gilroy?

@accidentalflyer @regulatorynerd Maybe it’s part of the Rivian collab effort.

@accidentalflyer Maybe they needed to pick up some pizza back to their innovation center?

@sp6runderrated Broadly I agree. I'd also note that TNG was on broadcast so there was a larger potential initial audience. And TNG on the whole is a positive show. Unlike The Shield which... uh... wasn't. If the rights ever get resolved, I'd recommend watching Homicide: Life on the streets

@dtc I don't think it is a coincidence that TNG does relatively well in syndication. This is partly due to being SiFi but mainly only being semi-siralized. You can pick up a TNG episode from any season and basically follow what is going on like a sitcom.

yup, and one other side note. Serialized dramas disappear fast. The time commitment for a serialized drama is far more than most novels. And that is why even great dramas tend to disappear quickly once their original run ends.

@sp6runderrated The Shield is the only show that I bought the Blu-ray set for because I figured it would disappear unlike other shows (ST:TNG) that will live on in some form forever. And yes I’ve never rewatched it.

I genuinely love The Shield. It is an amazing drama. It is over 88 hours long. That's an enormous time commitment for a show that went off the air almost 2 decades ago.

@SarahSluis My mind was blown when I saw this article last year npr.org/sections/healt… This whole situation has vibes you mention, but on super steroids (pun intended)

And also: the rebates / kickbacks / negotiations in the healthcare space give me total ad agency trading desk // principal-based buying vibes, amirite? When you are the one in power, but the benefits accrue to your customers/clients, it's hard not to want to reward yourself too.

1. My local, independently owned pharmacy closed last week. 2. The FTC is preparing to sue pharmacy benefit managers for antitrust reasons Turns out these two things are completely related. Here's why. thread 1/x

@constans Google Street view shows there were sidewalk vendors a decade ago at 86th and Broadway! And that account says they're 5th gen Manhattan? This person would probably have died if they went down to Chinatown or Hells Kitchen in the 1980s like I regularly did.

This would be the same “UWS” that has a “grand bazaar” in a parking lot full of trinket vendors and surrounded by more street vendors. You live in NYC. 5Th Avenue is full of sidewalk vendors selling fake LV bags. Did you think you were living in Alpine, NJ?

@AdtechGod (Third party) cookie

Heading out to Costco. You need anything?
