I guess you knew who created that index and for what purpose it was created. Unless S&P500 has a totally different way of measuring and view the stock market from the DOW, and then it will be a good reason to replace the DOW by S&P500. So why should we replace something by an offspring that share the same characteristic?
As an example, SBC was derived from AT&T and when SBC acquired his parent, they preferred to keep the parent's name (and I think they made a good choice), not the child's name.

Quote from jonbig04:
Out of curiosity, why do news agents, people, business channels etc all follow and quote the DOW? Isn't the S&P a far broader picture of our economy as a whole (which is always what they are talking about). I'm sure there are some advantages to the DOW, but in macro terms, shouldn't they be more concerned with the S&P? I don't care, just something I was always curious about.
