This is from the New York Times, October 2009, so it's a couple of years old. But it's really interesting. It shows that since three pointers were first introduced, they were first introduced in the 1979-1980 season, that three pointers have become more and more frequent. So what they are showing here is the average attempts per team season by season. It looks like there's just a steady upward trend here related to our question. There's a couple of anomalies here. The ones that really jump out are these three seasons in the late 90s.
