Facebook at 15: The long road to social media dominance

The 15 biggest stories from its first 15 years.

Facebook's come a long way since it launched 15 years ago today, on February 4th, 2004. Known as when it was created by Mark Zuckerberg and friends from Harvard, the service has gone from a "directory of information for college students" to a social media giant with more than 2.32 billion users every month. And that's not even counting people using services it acquired over the past few years, such as Instagram and WhatsApp, each with more than 1.3 billion users of their own.

But while Facebook has had plenty of impressive milestones in its history, it has also dealt with a good deal of controversies. From the Cambridge Analytica data privacy scandal to the spread of fake news on its site, Facebook has had to put out a lot of fires, especially in recent years. So, as the company turns 15, let's go back in time and take a look at 15 of the biggest Facebook headlines since it was born.
