Within the AdTech and digital media ecosystem, PwC has built a significant practice focused on media transparency, ad spend verification, programmatic auditing, and digital marketing transformation.

They help enterprise clients navigate the complexity of programmatic ecosystems, evaluate technology vendors, and build first-party data strategies in a post-cookie world.
