Suffer the children ...
Back in the 60s and 70s when I was a tiddler there were 3 (eventually) channels.
That meant that all tv broadcasting to all demographics had to be on those channels. Combine that with a lack of other entertainment beyond tree houses and books and that meant that the yoof was exposed to not only programmes aimed at them but also adult themes. Likewise, programmes aimed at, how can I put this, a lesser informed demographic, were side by side with full on intellectual documentaries. As a result, children and poorly educated people had their horizons expanded because they saw programmes outside of their experience and expectations (I lump myself in with this0. That was a GOOD thing. Now that one can spend 24 hours glued to a channel aimed totally at dim fools that is not happening anymore and as a result our 'culture' (such as it is/was) is dissolving!
