Brands have shifted their dollars. Digital advertising now claims over 80 percent of all US ad spending, according to Guideline's latest U.S. Ad Market Tracker. Traditional media has slipped below 20 percent. That’s a first.
In 2025, the ten largest companies accounted for 84.1% of U.S. internet advertising revenue, up from 80.8% in 2024, highlighting the increasing concentration of digital ad dollars among major platforms.
National TV took the hit. Last year’s World Cup set a high bar. In August, national TV ad spending dropped 13.4 percent compared to August 2025. The numbers show where the momentum is. It’s not with TV, print, or radio.
Most of the small growth in August came from the biggest players. The top 10 advertiser categories spent 2.4 percent more. All other categories together fell by 1.2 percent. Smaller brands are feeling the pinch. Weak consumer spending is making it harder for them. Big marketers keep pouring money into digital, chasing results they can measure.
Guideline’s 2025 outdoor advertising data shows that digital formats accounted for only 20% of U.S. outdoor ad spend, illustrating that digital penetration varies significantly by channel and that measurement methods can impact reported market share.
Guideline’s tracker is blunt. Digital is now the default. For media companies, this means changing how they sell and what they make. The days of a steady share for traditional media are over. Those who haven’t switched to digital-first are now on the sidelines. The numbers don’t lie. Digital’s hold on ad budgets is here to stay.
Industry analysts point out that digital’s rise isn’t even across all channels. Digital rules most of the market, but in outdoor ads, its share is still much lower. Each medium has its own story. The biggest advertisers are driving most of the gains. A recent industry analysis shows digital ad revenue is piling up with the major platforms.
