Let me think of others that have been "hacked":
NEW YORK (AP) - Major banks and credit-card issuers Capital One, Barclays Bank, U.S. Bancorp and Citigroup have joined the list of companies warning customers that hackers may have learned their email addresses.
The hackers also gained access to the email addresses of customers of JPMorgan Chase & Co., Best Buy Co., TiVo Inc., Walgreen Co. and Kroger Co.
