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
