Revenue over time

Estimated gross revenue accumulated across the whole catalogue, month by month. It climbs where a release finds buyers and flattens where a catalogue only coasts. The last point is the same figure as in the box above — gross, before Steam's cut, VAT and refunds. How this is estimated.
