A recent report, however, by Princeton researchers claimed that Facebook could take a dive in popularity over the next few years, similar to MySpace's decline.

Here's more from Sky News:

Facebook has hit its peak and could lose the vast majority of its users within three years, Princeton University academics say.

Interest in Facebook has peaked and the social network could lose up to 80% of its users by 2017, researchers say.

Academics at Princeton University used theories on the spread of disease combined with Google Trends data on searches for Facebook to predict the demise of the world's largest social network.

They concluded: "Facebook has already reached the peak of its popularity and has entered a decline phase.

"The future suggests that Facebook will undergo a rapid decline in the coming years, losing 80% of its peak user base between 2015 and 2017."

On Red Eye this morning, Greg Gutfeld and his panel of Andy Levy, Ellison Barber, Joanne Nosuchinsky and Paul Mecurio discussed what the future might hold for Facebook.

Levy, who abandoned Facebook, called the Princeton study "ridiculous" for using Google searches to form its conclusions.

"They did it based on Google searches for Facebook and they saw that that was really down. But people who use Facebook aren't Googling 'Facebook' so I don't really understand the study," he said.
