This holds for newspapers, buzzfeed, ESPN, reality TV vs. HBO/Netflix. And likely the web as a whole. The only way to survive off advertising content is cheap to produce, high volume content.
This means to have quality content either users pay per consumption (or use a flat fee monthly model), or other users produce it for you for cheap (ala YouTube).
It will be interesting to see what the subscriber numbers are once (if ever) people need to pay 2x or 3x what their initial teaser rate is.
