Supply does not affect Demand! At least, not using economics definitions... marketing affects Demand, or throttling Supply affects Price.

Not necessarily true. Sometimes there is no demand for something until the supply is there, especially with technology items. Who knew I wanted a PVR until they were actually available? The fact that it existed, created a demand.  I am sure I could word that better, but its the general jist of things.

According to "common sense", that might be true. Not with economic theory though.

Of course, I could be wrong, it's been a year since I took my last class for my econ minor.

Well it's been longer than that for me, although it wasn't my minor. The supply-side theory though was Say's Law, although I am more than willing to tell you there is no one and only in terms of accepting one economic theory over another, despite what the media tries to sell, and they are constantly evolving anyway. Just when one becomes dominant some other idea shows up again or re-emerges. So I wouldn't be surprised if some economic "camps" disagree.

The basic idea is that supply controls demand in that you can't really oversupply something, in a free market, because prices will just keep dropping causing demand to pickup again and essentially meet the supply. Naturally this doesn't take into account things like ability to buy or expense of providing the supply but the idea is sound. Another problem is economic theory works great in a bubble that you can study test, but then there is the reality which is interrupted by things like regulation and random events (not taking a position on those just stating what exists) which make a perfectly free market impossible.

Anyway, I threw in my own bit about the technology items some of which I read something about before, though I can't tell you from where.

it doesn't shift the demand curve.. but it definitely changes the amount of demand....... that's the very definition of moving along the curve.

for example (didn't include supply just to simplify things as we're only talking about price / demand)... price 5, demand 10.  Well, change the price to 1, and the demand is 52 ish.  Changing price always effects demand, unless it's a perfectly inelastic demand curve.. which would mean we were talking about drinking water or some one-of-a-kind cancer treatment.. and I don't think the dlc is that
