12 years after he famously dropped out of Harvard to run Facebook, Mark Zuckerberg finally returned on Thursday to receive his degree.
Zuckerberg will give the commencement address for his alma mater's class of 2017, making the 33-year-old CEO the youngest commencement speaker in Harvard's history.
You can watch Zuckerberg's speech live at 3 pm EST on his Facebook page, where it should also be available to view afterwards. The speech will also be streamed on Harvard's website.
Zuckerberg has been teasing his triumphant return to Harvard in a series of Facebook posts over the past week, including an old video shot by his dad that shows the moment he found out he had been accepted. On Wednesday, he and his wife Priscilla Chan visited his old college dorm room to reminisce about Facebook's early days and hot pockets.
"At tomorrow's commencement, I'll share what I've learned about our generation and the world we're all building together," he wrote in a Facebook post on Wednesday. "This is personally important to me and I've been writing it for a while."
