From lowly beginnings as a university campus students network in 2004 to global internet behemoth ten years later, Facebook has come a long way and become a part of millions of peoples' daily lives.

Facebook holds the title of largest online social network - in October 2013 Facebook reported that it now boasted 1.2 billion monthly active users with well over 150 billion 'friend' connections between them.

Somewhat unsurprisngly, the USA holds the record for most Facebook users by country, with 163,071,460 users as of March 10 2013. On the same day, according to the US Census Bureau, the population of the USA was 315,467,468, meaning that 51.69% of the US population had a Facebook account.

At the time, Brazil took second place in the rankings with 66,552,420 users.

"He [founder Mark Zuckerberg] always said Facebook was started not just to be a company, but to fulfil a vision of connecting the world," said Facebook's chief operating officer Sheryl Sandberg recently.

US president Barack Obama's re-election became a major social media moment when his update 'Four more years' gained the most likes in 24 hours - holding the record for ' most likes on a Facebook item in 24 hours' as well as 'most likes on a Facebook item'.

The undisputed queen of Facebook as far as fan pages are concerned is Barbadian R&B superstar Rihanna. As of January 2014, the singer had notched up over 85 million fans, making her the most “liked” person on Facebook. "It doesn't feel real...That's a lot of people to even think or imagine what it looks like together," she told journalist Brian A. Hernandez.

But with other emerging trends and platforms in social media, are Facebook's days numbered? As new trends and social networks arrive on the scene and favoured by a younger audience, some industry experts are predicting its downfall. Researchers from Princeton University, using models based on the lifespan of a disease epidemic, claimed it will lose 80% of its peak user base within the next three years.

However, Facebook's data scientist Mike Develin quickly and amusingly debunked this theory. Using the University's own methodology, he found that "our research unequivocally demonstrated that Princeton may be in danger of disappearing entirely."
