> I have to wonder why consumers so desire new content.
After watching kids grow, it struck me.
That's how we learn. New stuff = different stuff = learning. My kids would look at the floor for a bit as babies, it would be interesting. After a while, watching the same "old" tiles would become boring, not much to learn from there (color, hardness, temperature, grip, etc). So they'd start looking for lint, pebbles, bits of paper or dirt on the floor, cause that was new :-)
Content creation piggy backs on this intuitive understanding and hacks it, since as you say, old content can have great educational and entertainment value.
But I think it all boils down to "new = potential for learning" being wired into our brains.
