The Chinese government published an edict limiting children’s playing of video games to just one hour on only Fridays, Saturdays and Sundays. It is the authorities’ latest attempt to rein in what they view as the troublesome power of tech companies, though the government has long expressed concerns about gaming addiction among Chinese youth. Unlike previous decrees this one probably won’t hurt profits. Tencent, the biggest gaming company, generates only 2.6% of its total player spend from under-16s.
