Dan Poynter -LCB- 1 -RCB- quotes a publisher's survey of 1988, where the average
fiction book took 475 hours to write, publisher's average
annual sales were $ 420,000, and staff worked 50 hours a week.
While there is much to learn about the bestsellers in genre
fiction and what proportion is indie vs. legacy, and what their respective slices of the pie amount to be, extrapolating from that day to
annual income from
sales is a bit dicier.
