When Facebook was commercialised, it was just a collection of profiles. In 2016, it is one of the best news sharing platform, thanks to the News Feed feature which celebrated its 10th birthday on Tuesday.
At the beginning, a user could only visit a friend's page to look up some basic details about them but there was no way to see updates from all your friends or be sure they saw yours.
"With News Feed, all of a sudden you could share with all your friends at once. And you could see what was happening with all your friends in one place. News Feed was the first real social feed. It was such a fundamental idea that now, 10 years later, every major social app has its own equivalent of News Feed," Zuckerberg wrote.
Zuckerberg said that initially not everyone liked the idea and about a million people threatened to quit if Facebook was not changed back.
"I remember there were actual protesters in the streets outside our office demanding we change," he added.
According to Zuckerberg, News Feed has been one of the big bets Facebook has made in the past 10 years that has shaped the community and the whole internet the most.
"Technically, News Feed is one of the most advanced systems we have built. For more than 1 billion people every day, it considers everything your friends are posting and all of the media content you might be interested in, it considers how much you might care about updates from each person or interest, and then it tries to show you what you will find most important," he noted.
Nothing like it has ever been built before, Zuckerberg added.
