Lytics has introduced an ad targeting tool, Interest Engine, that defines a set of topics for each advertiser, uses the Google Protected Audiences API to store the topics relevant to each individual within their browser, and matches the topics against available advertisements.  Like all Protected Audiences applications, this approach enables creation of (relatively) large audiences without tracking known individuals.

No device is more mobile than an automobile.  Nielsen Gracenote is helping auto makers offer personalized entertainment with Nexus Auto, which uses Gracenote to translate metadata from different platforms, apps, and media types into a common language, making it easier to deliver content that matches user interests.  Nielsen positions this as helping auto makers build brand loyalty through a better experience, but you can bet there’s an advertising angle as well.

Amperity has launched Lakehouse CDP,  which delivers CDP functions within “lakehouse” data stores including Snowflake and Databricks.  Amperity tools for data modeling, data quality, identity resolution, generative AI, segmentation, and performance measurement will send all results to a company’s own lakehouse rather than a separate Amperity-managed database. Modules can be used independently but the real benefit here is that Amperity is one of the few “composable” CDP vendors who offer a complete set of pre-integrated CDP functions.
