I wonder how valuable this is as a metric, since much of what gets viewed is a function of art as much as it is marketing, production, or other elements. Some years studios make movies that are just bad--I wouldn't necessarily expect the income distribution to remain balanced across years.
Furthermore, these graphs don't appear to take into account the production cost of movies. If a low-budget film garners critical acclaim, it means more than a studio movie that just broke even, although their gross incomes could be pretty similar.
