The commission brought together 19 experts, from doctors to play campaigners, to act as commissioners and then held a series of evidence sessions hearing from children, parents and professionals around the country.
One of the key arguments experts made is that the rise in time spent on smartphones and gaming devices is being driven not just by the ubiquity of screens themselves, but by the loss of alternative ways and places for children to play.
From traffic-dominated streets to the huge decline in youth clubs and loss of funds for playgrounds, experts pointed to the decline in neighbourhood spaces where children could actually play freely.
Ingrid Skeels, co-director of Playing Out, was one of the 19 commissioners and has spent 15 years campaigning for children to have safer streets to play on.
