The document explores the multi-screen behavior of U.S. consumers, revealing that a significant amount of media time is spent across multiple devices, such as smartphones, tablets, PCs, and TVs. It identifies two primary modes of multi-screening: sequential usage (switching between devices) and simultaneous usage (using multiple devices at once), highlighting the smartphone as the most common starting point for activities. Research findings also indicate a high reliance on search to navigate between screens and a tendency towards multitasking, often resulting in split attention across devices.
