As chief executive of Facebook, a company that stretches across the globe and have more than one billion users, Mark Zuckerberg is always going to be in the media spotlight.
We take a look at some of the well known, and lesser well known, facts about the 33-year-old father of two.

What’s Mark Zuckerberg’s net worth?

Why does Mark Zuckerberg always wear grey?
Zuckerberg’s favourite grey T-shirt is always the same because he doesn’t want to waste time on “silly” decisions, according to a Q&A he did.
"I'm in this really lucky position where I get to wake up every day and help serve more than 1bn people, and I feel like I'm not doing my job if I spend any of my energy on things that are silly or frivolous about my life, so that way I can dedicate all of my energy towards just building the best products and services”, reported The Telegraph.
Why did Mark Zuckerberg learn Chinese Mandarin?
The motivations appear both personal and corporate. His wife’s family speaks Chinese Mandarin so there was a good incentive to learn the language to get to know them.
Facebook has also been trying to break into China and open up its potential market of 1.3 billion residents, but the country's rulers are currently blocking access to the social media site within China.
What’s about the rumour that Zuckerberg will run for President in 2020?
There’s been media speculation that Zuckerberg is considering running for President of the US in 2020 due to some of his recent hiring of staff and his movements around the states.
Two former members of campaign staff have been hired by Zuckerberg, and this year he is on a year-long 'listening tour'. This involves him travelling to all the states in the US and meeting with people in each; he's even using a former campaign staffer to document the trip.
However, Zuckerberg has denied any White House ambition in a Facebook post in May.
Why did he give away 99% of his Facebook shares
On the birth of their first daughter, Zuckerberg and Chan said they would give away 99% of their $45 billion (£30bn) fortune to good causes.
The donation, made in December 2015, was intended to cure disease, harness green energy, reduce poverty and promote equality. However, the noble sentiment came under fire due to the method of distributing his wealth.
Why is Facebook blue?
Zuckerberg suffers from red-green colour blindness but sees the colour blue most clearly, so it was an obvious choice when it came to choosing a colour for his brand, he told The New Yorker.
