Advertisers Target Audiences, Not Screens: Pubmatic Research

First-party data is also the punchline of this Advertiser Perceptions study on cross-screen video advertising, for Pubmatic.  Most (54%) of the publishers they surveyed said that advertisers care more about targeting audiences across screens than targeting on specific screens.  First-party data is what lets that happen.  Related: just 28% of programmatic ads are bought on the open market; others go through private marketplaces or negotiated deals, where more data is available.
