Concerns about the association of screen time with myriad developmental, health, and productivity outcomes in children and adolescents date back to the advent of screens themselves. The earliest of these studies was conducted in 1949 as a collaboration between the Columbia Broadcasting System (now known as CBS Corporation) and researchers from Rutgers University.Perhaps unsurprisingly, the study found that having a television increased family cohesion; did not promote viewer passivity; and did not replace other diversions, such as outdoor activities and socializing. 1 Few early television viewers would have imagined the role that screens play in our lives today. The modern age is marked by screen use for accomplishing a wide variety of tasks formerly unrelated to a screen. Talking to someone remotely, looking through magazines, reading a book, managing banking, playing games, and connecting with friends, all discrete activities before the current age, now frequently include some screen interaction. This proliferation of screen-based activities, all broadly accessible through a growing number of electronic devices (eg, mobile or smart phones, personal computers, or smart fashion such as watches or glasses), means that screens occupy a broad swath of daily life for many of us. Understanding the association between new technological affordances and human well-being and productivity outcomes, such as academic performance, is thus highly and perpetually salient.
