While doing some research this morning, I ran across this interesting tidbit.
Sony to donate to Haiti. In short, they announced on January 19th, a donation of $250,000 and an additional donation in maximum matching funds for its employees' contributions of $100,000. So grand total is $350,000 (well, $450,000 if you count the $100,000 the empolyees will have to give to get the matching donation).
This donation is in Sony's corporate name, not Michael's, and you can read the details here in Sony's blog.
