I thought Microsoft bought some Facebook stock, 1.6% for $240 million but I don't see them in there.
From the source link (reface.me, which actually got the picture from twitpic): "Not specifically included in the infographic are Microsoft’s 1.6% stake, Hong Kong billionaire Li-Ka Shing’s 0.8%, TriplePoint Capital (though as a debt provider they own nothing), and Accel Partners’ investment."
Many other persons are missing and probably classified as "Other". According to TechCrunch the Samwer Brothers from Germany also invested in Facebook. Would love to know how large their share is if they are still holding onto it.
nice to have a catch-all for your mistakes
(btw the mistake they made is that they are taking pre-dilution percentage figures from 5-6 years ago and adding them to more recent percentage figures, such as Goldman, and then completely forgetting other investors - such as MSFT (preferred stock!), Accel (first VC - preferred stock!). If you add all of these percentages, you would get over 200% - article is completely innacurate)
