In the early 80's, Reagan took over from Carter (please let's not start a politics discussion) and our economy pulled out of the general malaise. Technology really started to balloon, in the 90's, the internet age really expanded things, as well. Also, discount brokers made stock ownership easier (Kerim mentioned this). They've also changed the structure of the indices. Maybe inflation impacted things, as well? Just bringing up some ideas that may have contributed.
