Yup - but I think this is a stronger case with traditional distribution methods. Where marginal costs are higher and there are other fundamental limits (e.g. your local music store can only hold so many CDs).
The internet potentially has a significantly lower marginal cost. That channel is better suited to volume. (The expectation is that because you have n lower cost products, that people buy n rather than just one).
There's a limit as to how much users can buy/watch/listen to/afford though. That's the reason the whole long tail theory has been mostly evaporating anyway.
