Mobile accounts for 70% of programmatic streaming reach and spend
Ad-tech measurement platform Pixalate has launched its OpenEPG Index, a monthly ranking tracking programmatic ad spend and reach across over 5,000 streaming TV shows in the U.S. The initial data shows a surprising skew, with mobile (small screens) accounting for approximately 70% of both audience reach and programmatic ad spend compared to 30% for connected TVs.
Key Takeaways
- Mobile (small screen) viewing represents 69.5% of audience reach, with Android capturing 37% and iOS 33% shares.
- Connected TV (large screen) accounts for only 30.5% of programmatic audience reach and 30% of total spend.
- Nearly 46% of small-screen unique reach in May was driven by the sports genre, including talk and fan analysis shows.
- The sports-heavy Android/iOS top shows were led by 'Being Mary Jane' on BET and 'Indoor Football League' on Yahoo! Sports Network.
- Connected TV remains the dominant platform for reality TV (38%) and news (26%), with 'Diners, Drive-Ins, and Dives' topping the May ranking.
Why It Matters
The shift toward mobile viewing for professional streaming content indicates a significant blind spot in traditional measurement currencies. While legacy rankings emphasize TV-screen minutes, this data suggests programmatic buyers are aggressively following audiences into 'invisible' pockets like single-network apps and live mobile sports. For strategists, this creates a bifurcation in content performance: reality and news remain anchored to the large screen, while sports and drama are increasingly consumed on the go. As programmatic buying matures, the industry must decide if a 'TV show' is defined by its production value or the device on which it is viewed. Watch for whether agencies move to reallocate premium CTV budgets into high-engagement mobile video inventory.
Additional Context
The disparity between mobile and CTV measurement is a central point of contention in the 2026 media landscape. While Pixalate highlights mobile dominance in open programmatic channels, other trackers show a stronger CTV shift for premium on-demand content. Per YouTube’s 2025 'Big Bets' report, TV screens have officially overtaken mobile as the primary device for YouTube viewing in the U.S., a reversal of long-standing trends for the platform. This suggests that while programmatic and niche content may skew mobile, high-volume library content is consolidating on the large screen. Simultaneous multi-screening is further complicating the data. Per research from QUI Talks in May 2026, 67% of adults regularly use multiple screens, and 50% use their phone specifically while the TV is on. This creates a measurement 'overlap' where a user may be logged into a streaming app on both a handset and a smart TV. Advertisers are responding through cross-device attribution; for instance, Samsung Ads has begun tying CTV impressions directly to mobile actions such as site visits and store lookups to prove ROI. Financial stakes for shifting this measurement currency are high. Per eMarketer’s March 2026 forecast, U.S. CTV ad spend is projected to reach nearly $38 billion this year, yet Pixalate argues that current rankings leave 'massive segments' unmeasured. This measurement gap has led to several industry pivots, including the June 2026 announcement of a Fox and Roku partnership aimed at deepening integration between content and biddable inventory. As programmatic buying matures to account for roughly 50% of all CTV transactions, the industry is increasingly favoring private marketplace (PMP) deals over open exchanges to mitigate a CTV fraud rate that has reportedly tripled over the last two years.
