In Connected Life, a study of more than 55,000 internet users worldwide, TNS found that almost half of people (48%) who watch TV in the evening simultaneously engage in other digital activities, such as using social media, checking their emails or shopping online. The survey found ownership of about four digital devices each, rising to five among Australian, German and U.K. respondents. This, combined with demand for TV and video content on-the-go, is fuelling the rise of multiscreening or ‘screen-stacking’ – the use of multiple digital devices at the same time.
