  • "Of the total screen time, simultaneous use with TV is taking place around a third of the time. Millward Brown then breaks down simultaneous time into two categories: “stacking,” or using a digital screen for matters unrelated to the television, and “meshing,” which means using the second screen to enhance the TV experience. Those who stack tend to be filling time during ad breaks or watching TV somewhat halfheartedly. Those who mesh are mostly looking for more information or engaging in social media chatter about a show. Millward Brown says Americans are most likely to stack, while viewers in Thailand, the Philippines and South Korea are most likely to mesh.
