On Monday, one in seven people were using Facebook, that is a billion users who all logged in to their accounts in the space of 24 hours, Mark Zuckerberg said.
This is the highest number of people that have been on the social media platform since it launched in 2004 from Zuckerberg's room in Havard -- an indicator of how integral the site has become to daily interactions between people worldwide.
In a post on his timeline, he wrote:
"We just passed an important milestone. For the first time ever, one billion people used Facebook in a single day.
"On Monday, 1 in 7 people on Earth used Facebook to connect with their friends and family."
Two years ago, Facebook gained its billionth user, the BBC reports.
Zuckerberg explained "...this is just the beginning of connecting the world."
"I'm so proud of our community for the progress we've made.
"Our community stands for giving every person a voice, for promoting understanding and for including everyone in the opportunities of our modern world."
Zuckerberg's grand plans to connect the earth's seven billion plus people are not limited to the simple act of logging into your social media account.
In July it announced the completion of a solar-powered drone that aims to improve internet access in all parts of the globe.
In a blog for The Huffington Post, media commentator, Thomas Church speculated "what will happen when Facebook takes over the internet?'
"To the New One Billion Facebook will be the Internet. It won't be thought of as a separate website competing with others because it'll be the starting point of the web journey," he writes.
"Global corporations with consumer goods will have a new - and perhaps the only - way to reach these people meaning more money in Facebook's coffers but it'll also mean a rapid spread of foreign ideology such as consumerism."
