The buzz around Facebook's IPO has been going on for months, and there had been rumors of it happening for years prior. The Internet giant is planning for one of the largest IPOs in tech history, but the actual event might be postponed due to a series of acquisitions and other business, according to CNBC. The company had been planning for the launch to occur in early May, but now it could be as late as June.

CEO Mark Zuckerburg and his management team have been busy with acquisitions (like Instagram for $1 billion) and are less focused on preparing for the share sale. While some investors and traders are frustrated with the possible delay, Zuckerburg's focus on actual business could be considered a positive thing for the health of the company.

The acquisitions and the purchase of a patent portfolio from Microsoft for $550 million also required a refiling of some of the company's financial documents with the SEC, which could take an additional amount of time.

Interestingly, Groupon (Nasdaq: GRPN) experienced some issues prior to their IPO, and some investors are drawing parallels between the two companies. This is worrisome because Groupon's value drastically declined a short time after IPO -- and continues to do so.
