I decided to take a count of how many pages the last nearly 9 years of Playboy magazines have been. Makes for an interesting chart:
I think it’s interesting to see it declining over time (the black line is a linear trendline). If I’d had more time, interest, or data, I’d try to correlate to stock prices, count up advertising, etc. I do think it’s interesting to see that there’s typically one issue per year that’s quite substantially larger than the norm for the year (the December 2003 spike is because of the 50th Anniversary Issue).
