Media and The Stock Market

So I am just thinking out loud here, but is it possible that the increase coverage of the stock market and the economy is leading to a more volatile market. I mean over the last couple weeks we have seen the market bouncing up and down like a yo-yo. I am sure part of that has to do with the sub-prime fallout, corporate credit situation, etc. But over the last 20 years...hell even the last 5 years...we have seen incredible changes in the amount of finance news available to everyone. We have also seen incredible changes in the amount of trading and the speed of transaction. Could all of this be leading to a much more volatile and fickle market?
