Question about stock market?

[Sherlock Holmes]

I saw the film "The Social Network" where we come to know that Facebook didn't have advertisements once. If there are no advertisements then where did the money come from? I have some doubts.
Would you clear me?
Thanks in advance.

One place that I know of that the money came from was that Facebook has games where one can buy things. Why anyone would I do not know, but that is one cash flow for Facebook. Also people seem to be stampeding to invest money into facebook. Just a few days ago a couple of companies did.

But when they didn't have advertisements, they sold a lot of social data. You know;
