Facebook sees a billion users in a single day

Facebook on Thursday boasted of a new achievement with a billion people using the leading social network in a single day.

"We just passed an important milestone," chief executive and co-founder Mark Zuckerberg said in a post on his Facebook page.

"On Monday, 1 in 7 people on Earth used Facebook to connect with their friends and family."

It was the first time that a billion people used Facebook in a single day, according to Zuckerberg.

"When we talk about our financials, we use average numbers, but this is different," Zuckerberg said.

"This was the first time we reached this milestone, and it's just the beginning of connecting the whole world."

Zuckerberg also posted a video dedicated to the achievement.

In its earnings update last month, Facebook said monthly active users grew 13 percent from a year ago to 1.49 billion. The number of mobile active users rose to 1.31 billion.
