Social Media Advertising: With billions of active users, platforms like Facebook, Instagram, TikTok, and LinkedIn dominate social media ad spend. The ability to target audiences based on behavior and demographics makes this a critical channel for advertisers.
Video Advertising: Streaming platforms such as YouTube and connected TV services are driving video ad growth, as more consumers shift from traditional TV to digital formats.
Key Growth Drivers of Digital Ad Spend
Expansion of Internet Access
The growing penetration of internet services, particularly in emerging markets, is fueling digital ad spend. More than 5.6 billion people worldwide are now online, providing advertisers with an unprecedented opportunity to reach global audiences.
Rise of Mobile Advertising
Mobile devices account for the majority of internet traffic, making mobile advertising a dominant force. In-app ads, mobile search, and social media campaigns are expected to capture a significant portion of ad spend as consumers increasingly rely on their smartphones for shopping, entertainment, and communication.
Artificial Intelligence and Automation
AI-powered ad technologies are revolutionizing how campaigns are created, targeted, and optimized. Programmatic advertising—where AI automates the buying and placement of ads—has streamlined the process, increasing efficiency and ROI for advertisers.
Growing Adoption of eCommerce
The eCommerce boom has been a major driver of digital ad spend, with brands investing heavily in online campaigns to attract shoppers. Platforms like Amazon, Shopify, and Walmart’s digital marketplaces offer robust advertising solutions, allowing businesses to promote products directly to consumers.
Changing Consumer Media Habits
The shift from traditional media to digital platforms is accelerating. Consumers now spend an average of 7.5 hours per day online, engaging with content across social media, video streaming, and websites. Advertisers are meeting consumers where they spend their time, further driving digital ad growth.
Global Digital Ad Spend Forecast: 2026–2027
As digital advertising matures, its growth is expected to slow slightly but remain robust. By 2026, global digital ad spend is forecasted to reach $854.9 billion, reflecting a 7.0% annual increase, and by 2027, it is expected to surpass $910.3 billion, growing at 6.5% year-over-year. These figures underscore the sustained demand for digital marketing channels.
While growth rates may moderate, the sheer size of the market continues to expand. Key areas of focus for future growth include:
Connected TV (CTV): Advertising on streaming platforms like Netflix, Hulu, and Roku is poised for significant growth as traditional television audiences decline.
Influencer Marketing: Collaborations with social media influencers are gaining traction, offering advertisers a more authentic way to engage with niche audiences.
Augmented and Virtual Reality Ads: As AR and VR technologies gain adoption, innovative ad formats are emerging, creating new opportunities for immersive consumer experiences.
Digital vs. Traditional Media Consumption
Digital ad spend continues to outpace traditional advertising channels. The decline of print media, particularly newspapers and magazines, has been accelerated by the pandemic, while television advertising faces challenges from cord-cutting and the rise of streaming services. In contrast, digital platforms have capitalized on the shift in consumer habits.
In the United States, time spent on digital media has surpassed traditional formats, with consumers spending more hours daily on social media, streaming video, and mobile apps. This trend has reinforced the importance of digital ad investments for businesses looking to maximize their reach and ROI.

The global digital advertising market is on a trajectory of sustained growth, with expenditures nearing $800 billion in 2025 and projected to surpass $910 billion by 2027. Businesses continue to prioritize digital channels, driven by technological advancements, evolving consumer behavior, and the dominance of mobile and eCommerce platforms.
