Facebook is likely to disappear in the next five to eight years, according to Eric Jackson, founder of Ironfire Capital.

“In five to eight years they are going to disappear in the way that Yahoo has disappeared,” Jackson said. “Yahoo is still making money, it’s still profitable, still has 13,000 employees working for it, but it’s 10 percent 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. The first generation was big web portals, such as Yahoo. The second was the wave of social media with Facebook. The third generation is mobile, Jackson believes.

“Look at how Google has struggled moving into social, and I think Facebook is going to have the same kind of challenges moving into mobile,” he said.
