I don't understand articles like that. They all mention that the valuation for Facebook at $15 billion was from the $240 million investment for a 1.6 percent stake. But the $240 million was not just a purchase in the stake of the company it was also and advertising deal. Before someone can then come up with an evaluation from that transaction they need to break down how much of the $240 million was to purchase a stake and how much was for the advertising deal.
