Effect of media coverage on the exchange rate? When mainstream media or some high-profile blogs etc. report about Bitcoin, does it have a direct effect on the exchange rate?

Are there any examples in the past?

Let’s say an author is about to publish an article about Bitcoin in The New York Times. Would it be smart for the author to buy massive amounts of Bitcoin immediately before publishing the article, in the hope that the exchange rate rises?
There is no way to attribute Bitcoin price changes to news coverage with precision. Because you can never know the exact reason people are buying or selling.

The situation in Cyprus coincided with Bitcoin price skyrocketing to $245. There were lost of news covering both subjects at the same time but we don't know for sure.

It is logical though, to think that Bitcoin related news does have an impact on Bitcoin price. Especially high profile news and articles on high profile media. But, the content and the tone of the news/article will make a huge difference.

NYT article might push the prices up if it has a positive or even informative tone. It might also cause a drop in prices if it has a negative tone.

The larger the economy the harder it will be to manipulate the price.
