Microsoft's Xenix license was similar; it probably got down to $1 or 50c per copy. The price per copy went steeply down as you sold more copies; the licenses soaked the small sellers and catered to the large volume sellers. After all, it cost AT&T *nothing* for a company to sell twice or ten times as many copies; they weren't supporting the software anyway. As I recall, when Microsoft supplied the OS for the TRS-80 Model 16, they blew the doors off all the tiers in their UNIX license. The 16B sold 40,000 copies in 1984 (according to Wikipedia), making it the highest volume UNIX computer of the year. Clueless monopolist business people at AT&T had never anticipated that ANYBODY would sell 40,000 copies of UNIX. Remember when IBM estimated in 1943, "I think there is a world market for maybe five computers" and DEC in 1977 said "There is no reason anyone would want a computer in their home"? See: https://www.pcworld.com/article/155984/worst_tech_predictions.html After the first few years, Sun was shipping high volumes of UNIX systems (tens or hundreds of thousands per year). For many years they didn't need any of the later USL licenses, because they shipped a BSD UNIX that they were maintaining themselves, and that was (in many peoples' opinions) higher quality software than anything that USL was offering. The licensing for the ancient 32V license they needed was written back in the days when shipping 100 copies was a big deal, so the prices at the 1,000 or 10,000 or 100,000 copy tiers were very cheap. Adding 1c to ship ditroff rather than troff might have been reasonable, but not $5! John
