#1Programmatic advertising has captured 91%+ of US digital display spending (eMarketer 2024), and is aggressively expanding into connected TV (CTV programmatic reached ~$30B in 2025), digital audio (Spotify, Pandora programmatic), and digital out-of-home. Header bidding and supply-path optimization have further automated inventory allocation, eliminating even the publisher-side sales roles that once managed programmatic deals manually.
