This document discusses the challenges that traditional advertising agencies face in adapting to the digital marketing landscape. Some key points: 1) Advertisers and agencies apply traditional practices without understanding digital norms, creating inefficiencies. 2) The digital space requires different skills, talent is scarce, and relationships between costs have changed. 3) Agencies must determine the right service model for their clients' needs around production, strategy, buying, and more. 4) Compensation models are moving from retainer-based to include more performance incentives and output-based scopes of work.
