There's a whole 'sub'-culture around very young (as in, pre-teenage) toy and unboxing vloggers who have got themselves (and/or have been enabled by parents) on to this YouTube production treadmill (not exclusively YT, but Insta, too). The self- and peer-generated pressure to increase views, shares, total viewing time, and in turn, churn out fresh and engaging content and the requisite social engagement is relentless, even if it's not on the same scale of these YT celebs. It's perhaps greater in some ways, due to the shoestring nature of most of them, lacking the specialist skills and resources to work productively, and having to wear multiple hats that professional content producers co-ordinate through a team. It's a massive time-suck on parents and children; I can't help but think there are going to be some latent consequences to this wide-scale phenomena amongst schoolchildren.
