By 2023, CMOs will spend nearly $150 billion on search marketing, banner and outstream advertising, instream advertising, and email marketing in the US. Paid search will lose share to shopping and voice search; programmatic banner buys will retrench; television innovation will drive instream growth; and email will woo B2B adopters. These changes reflect budget priorities that vary by marketer sophistication and digital marketing experience. Growth will improve workplaces, agency relationships, and retail outlets.
