Ad Tech Briefing: Disney and Mediaocean sound the death knell for the I/O
The pact suggests the insertion order is on borrowed time and is a pitch to the CFO as much as it is to the CMO

Disney and Mediaocean's recent announcement of a partnership to streamline ad space purchases on the House of Mouse has sparked discussions about the future of the insertion order (I/O) in the advertising industry. The pact, which is set to roll out in Q3 with the launch of Prisma Direct, a new workflow layer within Mediaocean's Prisma system, aims to directly connect media buyers and publishers through API-driven integrations. While this development may seem like a minor change, it signals a broader trend of compression in the media supply chain, accelerated by AI in recent years.
The insertion order, a longstanding practice in the industry, has been a point of contention for some time. It involves advertisers specifying the order in which their ads should appear alongside competitors' ads on a publisher's platform. This system has been criticized for being inefficient and costly, with some arguing that it adds unnecessary complexity to the advertising supply chain. Disney and Mediaocean's partnership suggests that the insertion order is on borrowed time and is a pitch to the CFO as much as it is to the CMO.
The House of Mouse, Disney's ad sales platform, has historically been notorious for its complex I/O process, which has made it difficult for advertisers to purchase ad space efficiently. By partnering with Mediaocean, Disney aims to simplify this process and make it more streamlined. Prisma Direct, the new workflow layer, will enable direct connections between media buyers and publishers, bypassing the need for insertion orders. This could potentially reduce costs and improve efficiency in the advertising supply chain.
The trend towards compression in the media supply chain has been evident for some time. As the industry has become more digital and data-driven, there has been a push to eliminate inefficiencies and reduce costs. AI has played a significant role in this shift, enabling more sophisticated targeting and real-time bidding. The Disney-Mediaocean partnership is another step in this direction, as it seeks to further streamline the advertising process and reduce reliance on outdated systems like insertion orders.
While some may view this development as a positive step towards efficiency, others argue that it could have broader implications for the industry. The decline of insertion orders could lead to a more centralized and consolidated advertising market, with larger players dominating the supply chain. This could potentially limit the ability of smaller publishers and advertisers to compete and could lead to reduced innovation in the industry.
Despite these concerns, the Disney-Mediaocean partnership represents a significant shift in the way ad space is purchased and sold. By directly connecting buyers and publishers, Prisma Direct could pave the way for a more efficient and cost-effective advertising ecosystem. As the industry continues to evolve, it will be interesting to see how this trend plays out and what impact it has on the future of advertising.
In conclusion, Disney and Mediaocean's partnership to minimize the headaches of purchasing ad space on the House of Mouse is a clear indication that the insertion order is on borrowed time. The launch of Prisma Direct, a new workflow layer designed to directly connect media buyers and publishers, represents a significant step towards a more efficient and streamlined advertising supply chain. While this development may have its challenges, it also holds the potential to drive innovation and improve the overall efficiency of the industry. As the industry continues to adapt to new technologies and changing consumer behaviors, partnerships like this are likely to become more common, reshaping the way we think about advertising and the role of insertion orders in the future.
