Back, you know, a few generations ago, people didn't have a way to share information and express their opinions efficiently to a lot of people. But now they do. Right now, with social networks and other tools on the Internet, all of these 500 million people have a way to say what they're thinking and have their voice be heard.
Video is growing very quickly on Facebook. A lot of people compare that to YouTube. I think that kind of makes sense. YouTube isn't the only video service, but I think it's the biggest, and it probably makes more sense to compare Facebook video to YouTube rather than Netflix because that's a completely different kind of content.
What we figured out was that in order to get everyone in the world to have basic access to the Internet, that's a problem that's probably billions of dollars. Or maybe low tens of billions. With the right innovation, that's actually within the range of affordability.
When most people ask about a business growing, what they really mean is growing revenue, not just growing the number of people using a service. Traditional businesses would view people using your service that you don't make money from as a cost.
This is our commitment to users and the people who use our service, is that Facebook's a free service. It's free now. It will always be free. We make money through having advertisements and things like that.
People have really gotten comfortable not only sharing more information and different kinds, but more openly and with more people - and that social norm is just something that has evolved over time.
I always kind of see how I want things to be better, and I'm generally not happy with how things are or the level of service that we're providing for people or the quality of the teams that we built. But if you look at this objectively, we're doing so well on so many of these things. I think it's important to have gratitude for that.
Facebook is inherently viral. There are lots of sites that include a contact importer, and for lots of them it doesn't really make sense. For Facebook it fits so well. It wasn't until a few years in that we started building some tools that made it easier to import friends to the site. That was a huge thing that spiked growth.
Facebook is really about communicating and telling stories... We think that people can really help spread awareness of organ donation and that they want to participate in this to their friends. And that can be a big part of helping solve the crisis that's out there.
We're a community of a billion-plus people, and the best-selling phones - apart from the iPhone - can sell 10, 20 million. If we did build a phone, we'd only reach 1 or 2 percent of our users. That doesn't do anything awesome for us. We wanted to turn as many phones as possible into 'Facebook phones.' That's what Facebook Home is.
I spend a lot of time just, you know, with my girlfriend and my dog. And I mean, we don't have a lot of furniture in our house, so it's really simple. And we're trying to build products for everyone in the world, right. And you don't want to get isolated to do that.
It's a juicy thing to say we're building a phone, which is why people want to write about it. But it's so clearly the wrong strategy for us.
The companies that work are the ones that people really care about and have a vision for the world so do something you like.
I updated my grilling app, iGrill, today and it now has Facebook integration that lets you see what other people are grilling right now around the world. Awesome.
Building a mission and building a business go hand in hand. The primary thing that excites me is the mission. But we have always had a healthy understanding that we need to do both.
Working with a lot of people at the same time is a task. I really like making stuff and getting stuff done. One of the things I really liked about Facebook was that I could always move so quickly. I wrote the original application in, like, nine days at the end of January.
The majority of people who don't have Internet, don't have the Internet because they don't know why they want to use the Internet.
The main Facebook usage is so big. About 20 percent of the time people spend on their phone is on Facebook.
We pay attention to every demographic in every country, so we're going to focus on building things that teens are going to like, and we're also going to focus on building things that other folks are going to like.
If you look at the history of our country over the last 100 years, there have been periods where science and research have been celebrated. They were really kind of held up as heroes in society, which encouraged a generation of people to go into these fields.
We're very focused on making News Feed really good, making our photos experience really good, making messaging really good, and creating great location apps. That's the nature of a platform business of our scale. Most companies that are relevant to us will have some overlaps in some competitive way.
The real question for me is, do people have the tools that they need in order to make those decisions well? And I think that it's actually really important that Facebook continually makes it easier and easier to make those decisions... If people feel like they don't have control over how they're sharing things, then we're failing them.
A squirrel dying in front of your house may be more relevant to your interests right now than people dying in Africa.
Once you have a product that you are happy with, you the need to centralize things to continue growth.
Facebook was not originally created to be a company. It was built to accomplish a social mission - to make the world more open and connected.
The question isn't, 'What do we want to know about people?', It's, 'What do people want to tell about themselves?'
Bill Gates has always been a mentor and inspiration for me even before I knew him. Just growing up, I admired how Microsoft was mission-focused.
All of my friends who have younger siblings who are going to college or high school - my number one piece of advice is: You should learn how to program.
Our mission is to connect every person in the world. You don't do that by having a service people pay for.
I will only hire someone to work directly for me if I would work for that person. It's a pretty good test.
People don't care about what someone says about you in a movie - or even what you say, right? They care about what you build. And if you can make something that makes people's life better, then that's something that's really good.
When I was in college I did a lot of stupid things and I don't want to make an excuse for that. Some of the things that people accuse me of are true, some of them aren't. There are pranks, IMs.
Right now, with social networks and other tools on the Internet, all of these 500 million people have a way to say what they're thinking and have their voice be heard.
Advertising works most effectively when it's in line with what people are already trying to do. And people are trying to communicate in a certain way on Facebook - they share information with their friends, they learn about what their friends are doing - so there's really a whole new opportunity for a new type of advertising model within that.
I actually do think you're seeing this trend towards organizations just caring more about their brand and engaging. And so I think Home Depot will want to humanize itself. I think that's a lot of why companies are starting blogs, are just giving more insight into what's going on with them.
Facebook is uniquely positioned to answer questions that people have, like, what sushi restaurants have my friends gone to in New York lately and liked? These are queries you could potentially do with Facebook that you couldn't do with anything else, we just have to do it.
We're at a point now where we've built AI tools to detect when terrorists are trying to spread content, and 99 percent of the terrorist content that we take down, our systems flag before any human sees them or flags them for us.
