You've got that right. Look at all that changed in 15 years in terms of what it took to garner $43,000 in revenue compared to doing the same now. An independent developer can, in less than the time it took Dr Koop to hit that number, hit the same number with 1/1000th (if not 1/10,000th) of the capital outlay (their $8 million in money), and nary a Microsoft product in sight. Between fifteen years of open source, competition for infrastructure and platform as a service, multiple revenue channels available to individuals and several orders of magnitude more eyeballs and attention spent on the internet, we can all party like it's 1997.
