It had over 3.5 Million page views the first week. Estimates are that it took about three man-months to write and design the long article. But that was two years ago, and without any of the tools and experience they have now.
That's expensive, but napkin-calculations can be done:
Average yearly at NY Times according to Google is: $98 167 That means about $33 000 plus some taxes and costs for three monte, say, $50 000 then.
Can you sell one ad space in such an article at $50 000 / 3 500 000 = $14.29 per 1k impression?
NY Times sells ads at $6.29 for 1k impression on their sports pages. On the Snow Fall article three such ads would be enough to cover the estimated costs.
As a comparative note: A full page print ad costs $10 per estimated reader, it is possible that this Norway article is also published in the regular print, and will therefore recuperate some costs there as well.

To keep the analogy, NY-times is doing web-page stories Broadway-style. Perhaps they found an unexplored marked, perhaps it is too soon. But sooner or later, the art-form of story telling on the web is going to be taken to the next level done by professionals for a lot more money than any amateurs telling the same story.
In fact, I'm betting on it by trying to find a market for being the creator of things like this. I haven't gotten started yet, but it's at the top of my 'business opportunities' list. I think I mostly just need to find someone who is good at visualizing data, or dive into that myself.
