Has the increased demand for synchronous, high-bandwidth activities—like video meetings—affected device use? Are people choosing one device over another for such activities? This TUPdate reports on synchronous and asynchronous communication levels by country alongside device type (smartphone, home PC, or tablet), activity type (phone/video calls, text message, email, and web-based group meetings), and age group. This TUPdate considers online adults in the US, UK, Germany, and Japan from TUP/Technology User Profile 2020, which is TUP’s 38th annual.
