Podcast platform Acast has launched a different flavor of audience-based targeting: it matches its own identify graph of podcast listeners with advertisers’ customer lists. The new capability doesn’t rely on cookies or device IDs, but does use IP address, which European regulators are now treating as personal data.  But that’s okay: the new service is only available in the U.S. and Australia.

In partnership with attention metrics provider Adelaide, The Trade Desk is now offering high attention inventory to advertisers. Attention — often based on reactions of opt-in panels to ads — is now competing with viewability as a valued attribute, and is being used to complement contextual metrics. Attention has been used in the past to test ads once they have been published; now it’s entering the pre-bid space.
