An AP report (July 2, 2008) cites the Wall Street Journal which mentions that Microsoft is expanding discussions with other media players such as News Corp, and Time Warner in order to create a deal with Yahoo.
According to the report a three party deal would provide Microsoft with Yahoo’s search engine, while the remaining Yahoo businesses would be combined with News Corp’s My Space or Time Warner’s AOL.
Keep in mind Yahoo, Google, and MySpace are already partnering together on standards in the social networking arena with the OpenSocial Foundation (McCarthy,2008), and at one time News Corp considered a swap deal with Yahoo whereby News Corp would give MySpace to Yahoo in return for a 30% controlling interest in the combined new Yahoo business.

What is the market reaction to security breaches and issues?
In terms of economic impact and market reaction, a 2003 study by Campbell, Gordon, Loeb and Zhou provided evidence to suggest that firms are significantly punished by the stock market only when security issues involve confidential information or unauthorized access to private information such as customer lists, credit card data, and company secrets. If the security issues are of a non-confidential nature such as denial of service attacks, and viruses, then sampling in the study suggests trivial stock market reaction.
The data that was sampled/tested in the study spanned the years 1997-2000 and involved publicly disclosed security incidents that were reported in either the Wall Street Journal, New York Times, Washington Post, USA Today, or Financial Times.
I wonder if data samples from 2000-2007 would remain in-line with previous empirical findings, or if revenues/sales were impacted versus just the stock price?
