The New Network Effect: Redefining the Agency-Publisher-Data Dynamic

As media dollars continue to flow away from linear channels and into CTV, how agencies, publishers and data providers work together is undergoing historic — and continued — change. 

In this webinar, senior leaders from Viant, Active Media Services and TransUnion met to explore how the convergence of premium content, precision targeting, and curated, addressable inventory is creating a powerful CTV network effect, reshaping the ways that both sides of the transaction achieve their goals and maximize impact.  

You’ll discover: 

• What shifting viewership behaviors mean for media planning across linear and CTV 

• How curated CTV ecosystems drive smarter investments and better outcomes 

• Why premium inventory and interoperable data are key to unlocking the full value of CTV 

• The evolving role of data as it flows across platforms, agencies, and publishers
