The rise of YouTube has certainly resulted in some simpler content becoming less usable. While installing a new thermostat, I googled "4 wire thermostat colors" a while back and got an onslaught of videos that were each several minutes in length. It's literally 4 pieces of information, that's it. It's made worse by Google promoting YouTube results, since it probably drives more ad revenue.
On the other end of the spectrum, when I look for information about how to assemble a transmission (or similar) I instead find someone who has cut together some short video that doesn't actually contain good shots of the various assembly steps.
