The digital advertising industry in the U.S. achieved a significant milestone in 2024, as total internet advertising revenues surged to a record-breaking $258.6 billion, according to a new report from IAB. This marks a substantial 14.9% increase from the previous year, driven by innovative advertising technologies and a robust political and sporting calendar.

2024 saw impressive growth across all quarters, with the highest increase in the first quarter at 15.7%. The growth was consistent throughout the year, despite global economic uncertainties and the ongoing challenges of evolving consumer privacy regulations. The latter half of the year maintained a steady pace, contributing 54% to the total annual revenue, underscoring the sector's resilience and the strategic shift towards year-round advertising efforts.

Podcast advertising stood out with a remarkable 26.4% growth, fueled by an evolving media consumption landscape where on-demand audio content has become more integral to daily routines. This medium has proven especially effective for political advertisers in an election year, demonstrating the unique ability of podcasts to engage with niche audiences.

Digital video advertising emerged as the fastest-growing segment, with a 19.2% year-over-year increase to $62.1 billion. This format now accounts for 24.0% of the total ad revenue, reflecting the shift towards more dynamic and engaging advertising mediums. Meanwhile, search advertising continued to dominate, reaching $102.9 billion and growing by 15.9% from the previous year.

Programmatic advertising also saw notable gains, reaching $134.8 billion in revenue, up 18.0% year-over-year. This growth highlights the increasing reliance on automated and data-driven ad placements that optimize real-time bidding and targeting.

Social media platforms rebounded strongly from a slower 2023, with advertising revenues jumping 36.7% to $88.8 billion. The resurgence was aided by the presidential election and the Olympics, which traditionally boost advertising expenditures.

Commerce media, particularly through retail media networks, also saw significant growth. Advertising revenues in this sector climbed 23.0% to $53.7 billion, driven by advertisers leveraging first-party data to navigate the changing landscape of consumer privacy and targeted advertising.
