Eight hundred million users have helped to make Facebook's IPO the hot topic of the year and the largest tech IPO in history.

The Internet giant recently filed its official paperwork with the Securities and Exchange Commission for an offer of $5 billion. Many investors believe that number could easily double at IPO. "Either way, it is poised to become the biggest Internet-related IPO on record," reports CNBC.

In all, the social media behemoth expects its valuations to land between $75 and $100 billion. This is certainly a record-breaking figure for Internet IPOs.

It is worth noting that only 6 of the 10 largest Internet IPOs are still around: Genuity, CompuServe, Savvis Communications, and McData were all bought out by other companies.
