And while that assertion has raised a ruckus online this week, other industry analysts wouldn't be shocked if the prediction comes true.

"In five to eight years they are going to disappear in the way that Yahoo has disappeared," said Eric Jackson, founder of Ironfire Capital . "Yahoo is still making money. It's still profitable, still has 13,000 employees working for it. But it's 10% of the value that it was at the height of 2000. For all intents and purposes, it's disappeared."

Jackson noted that so far there have been three generations of Internet companies. Yahoo, a Web portal, is a great example . Facebook then swept in as the second generation with the wave of social media. The third generation is all about mobile.

One of the problems for Facebook is that the company has not been able to monetize its . Company executives even raised the issue in its pre-IPO filings with the U.S. Securities and Exchange Commission this spring.

And that could really hold the company back and give others a chance to flourish in its place.
