The chart displays the US Retail Digital Ad Total Engagement (%) from 2020 to 2025, illustrating that the overall engagement across all devices remained at a constant, maximum level throughout the six-year period. The Total Engagement (%) was consistently 100% in 2020, 2021, 2022, 2023, 2024, and 2025. This suggests that all retail digital ads delivered across devices are considered engaged or viewed according to the defined metric. The lack of variation in the 100% figure across the years indicates a ceiling effect has been reached for total ad engagement in the US retail sector.
