IMDb es un ejemplo, ¿de qué tipo de fuente de suministro?

IMDb is an example of an Amazon Owned and Operated (O&O) property. Amazon O&O properties are websites and apps directly owned and operated by Amazon, such as IMDb, Twitch, and Amazon.com itself. These properties offer advertisers unique access to Amazon's audience data and inventory. Third-party exchanges are independent ad exchanges that aggregate inventory from various publishers. Amazon Publisher Services (APS) is Amazon's own supply-side platform (SSP) that helps publishers monetize their inventory, including non-Amazon O&O sites. Private Marketplaces (PMP) are curated deals between a publisher and a select group of advertisers, offering more control than open exchanges but not necessarily being Amazon-owned.
