On July 27, 2026, InMobi Advertising announced FRAME Attention, a certified high-attention media product for mobile in-app video and Connected TV (CTV), which Lumen Research validated. The product, launched on July 24, 2026, aims to allow advertisers to purchase campaigns based on attention rather than viewability, and demonstrated that its video ads achieve 3.5 times more attentive seconds compared to YouTube equivalents, promising a minimum floor of 8,000 Attention Per Mille. Earlier, on July 26, 2026, Lumen Research, in partnership with Mail Metro Media and Havas Media Network UK, released a study finding that digital environments with lower ad loads drive more attention, improve brand recall, and increase purchase intent.
